What are geometric shapes?
In Mathematics, Geometric shapes are the figures which demonstrate the shape of the objects we see in our everyday life. In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes.
Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as a square, circle, etc. Irregular shapes are asymmetrical. They are also called freeform shapes or organic shapes. For example, the shape of a tree is irregular or organic.
In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc. In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can observe all these shapes in our daily existence also. For example books (cuboid shape), glasses (cylindrical shape), traffic cones (conical shape) and so on.
Now,
As we know, If two lines intersect and make an angle, say X=45°, then its opposite angle is also equal to 45°.
The same theorem is applied here
hence
The opposite angles ∠1 and ∠4 equal.

Answers
830.72 sq in of wrapping paper does Tiana need to buy.
What is surface area of a cylinder?
The formula for the surface area of a cylinder is
SA = 2πr^2 +2πrh = 2πr(r +h)
To find the total area of wrapping paper needed for one box, Tiana needs to add up the area of each of the six sides. The area of the top and bottom is,
22.2 inches * 4.8 inches = 106.56 square inches.
The area of each of the four sides is 14 inches * 22.2 inches = 308.8 square inches.
So, the total area of wrapping paper needed for one box is,
106.56 + 308.8 = 415.36 square inches.
Since, Tiana needs to wrap 2 boxes, she needs to buy twice that amount, which is 2 * 415.36 = 830.72 square inches.
Rounding to the nearest hundredth, Tiana needs to buy 830.72 sq in of wrapping paper.
Hence, 830.72 sq in of wrapping paper does Tiana need to buy.

Find a linear approximation to the function f(x)= e^(x/500)
for the range of values O< x <100. Do this by making the linear approximation equal to the function at the end points x=0 and x=100.
Find the percentage error in the approximation when
(a) x = 25
(b) x = 50
Answers
(a)The percentage error is 0.123%.
(b)The percentage error is 0.049%.
Find the equation of the tangent line at the point (0,f(0)),
⇒ f(x) = exp(x/500)
⇒ f'(x) = 1/500 exp(x/500)
⇒ f(0) = exp(0/500)
= 1
So the equation of the tangent line at x = 0 is,
⇒ y = f(0) + f'(0)(x - 0) y
= 1 + 1/500x y
= x/500 + 1
Find the equation of the tangent line at the point (100,f(100)),
⇒ f(x) = exp(x/500)
⇒ f'(x) = 1/500 exp(x/500)
⇒ f(100) = exp(100/500)
= exp(1/5)
So the equation of the tangent line at x = 100 is,
⇒ y = f(100) + f'(100) (x - 100)
⇒ y = e^(1/5) - (1/500)(x - 100)
⇒ y = -x/500 + exp(1/5) + 1
Now we can use these two equations to approximate the function f(x) for 0 < x < 100.
For example, when x = 25
⇒ y = x/500 + 1
⇒ y = 25/500 + 1
⇒ y = 1.05
And the actual value of f(25) is,
⇒ f(25) = exp(25/500)
⇒ f(25) = exp(1/20)
⇒ f(25) ≈ 1.0513
So the percentage error is,
⇒ |1.05 - 1.0513| / 1.0513 x 100% ≈ 0.123%
We can repeat the process for x = 50 and find that the percentage error is 0.049%.

the two shorter sides of a right triangle have lengths 8.49 meters and 1.61 meters. what is the length of the hypotenuse?
Answers
The length of the hypotenuse is: 8.64 meters
The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that;
In any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
The Pythagorean theorem can be defined as; fundamental theorem in mathematics that relates to right triangles.
In this case, the two shorter sides have lengths 8.49 meters and 1.61 meters, so the length of the hypotenuse can be found by calculating the square root of the sum of the squares of these lengths:
i.e. √(8.49^2 + 1.61^2) = √(72.0201 + 2.5881) = √74.6082 = 8.64 m
So, the length of the hypotenuse is approximately 8.64 meters.

What is a triangle?
In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.
Based on the sides of a triangle, a triangle is classified into 3 types, namely:
Scalene Triangle – All the sides are of different measures.
Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.
Equilateral Triangle – All the 3 sides of a triangle are of the same measure.
Based on the angles of a triangle, a triangle is classified into 3 types, namely:
Acute Angle Triangle – All the angles of a triangle is less than 90°.
Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.
Right Angle Triangle – One of the angles of a triangle is equal to 90°.
Now,
According to Pythagorean theorem,
H^2=P^2+B^2
Where H=hypotenuse, B=base, P=Perpendicular
Given base=16
let perpendicular=x then hypotenuse=x+2 as The lengths of the other two sides are consecutive odd integers
Therefore, (x+2)^2=x^2+16^2
x^2+4+4x=256+x^2
x=63 and x+2=65
Hence,
The smaller side of the triangle from missing sides is 63cm.

What is percentage ?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used.
The formula to calculate the future value of an investment is:
FV = PV * (1 + r/n)^(nt)
where:
PV = present value = $1,000
r = annual interest rate = 8.25%
n = number of compounding periods per year = 12 (monthly)
t = number of years = 3
FV = $1,000 * (1 + 0.0825/12)^(12 * 3)
Plugging in the values and using a calculator, we get:
FV = $1,000 * (1 + 0.0825/12)^(12 * 3) = $1,000 * (1.006866)^36 = $1,000 * 1.281216 = $1,281.216

A ball is launched from a 190.4-foot tall platform. The equation for the ball's height h at time t seconds after launch is h (t) = - 16t? 1.6t + 190.4, where h is in feet. What is the maximum height the ball achieves before landing?
Answers
Answer: 191.8 feet
Step-by-step explanation:
The equation for the ball's height h at time t seconds after launch is h(t) = -16t^2 + 1.6t + 190.4.
To find the maximum height the ball achieves before landing, we need to find the maximum value of h(t). To do this, we need to find the vertex of the parabola represented by the equation. The vertex of a quadratic equation in the form of y = a(x-h)^2 + k is (h, k), where h is the x-coordinate of the vertex and k is the y-coordinate of the vertex.
We can find the x-coordinate of the vertex by using the formula:
h = -b/2a
Here, a = -16, b = 1.6, and c = 190.4
Plugging these values into the formula:
h = -1.6/2*(-16) = 1/8
The x-coordinate of the vertex is 1/8 of a second, which is the time at which the ball reaches its maximum height.
To find the y-coordinate of the vertex, we can plug in the value of t = 1/8 into the equation for h(t):
h(1/8) = -16(1/8)^2 + 1.6(1/8) + 190.4
This gives us the maximum height that the ball achieves before landing, which is approximately 191.8 feet.

Answers
A non-fruitful function which makes a turtle draw an equilateral triangle is given in the explanation.
Here is an example of a non-fruitful function in Python that takes a turtle object and a size as arguments and makes the turtle draw an equilateral triangle:
import turtle
def draw_triangle(some_turtle, some_size):
for i in range(3):
some_turtle.forward(some_size)
some_turtle.left(120)
# Create a turtle object
t = turtle.Turtle()
# Call function to draw an equilateral triangle of size 100
draw_triangle(t, 100)
# Hide turtle and exit the turtle window
turtle.done()
This function makes the turtle move forward by some_size units and turn left by 120 degrees three times, resulting in a triangle with three equal sides and three 60-degree angles.
