If m∠RTG = 5.8° and m∠GTU = 113.6°. Then the measure of the angle ∠RTU will be 119.4°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Adjacent angle - In math, two points are nearby in the event that they have a typical side and a typical vertex.
Angles RTG and GTU are adjacent angles. If m∠RTG = 5.8° and m∠GTU = 113.6°.
∠RTU = ∠RTG + ∠GTU
∠RTU = 5.8° + 113.6°
∠RTU = 119.4°
The measure of the angle ∠RTU will be 119.4°.

Find the distance between the two points rounding to the nearest tenth (if necessary).
(-6, -6) and (-8, 2)
The distance between the two points is 8.25 units
What is meant by the distance between two points?The distance between two points in a plane is the length of the line segment separating the two locations. Typically, the equation d=((x2 - x1)2 + (y2 - y1)2) is used to calculate the distance between two locations. You may use this formula to get the separation between any two points on an x-y plane or coordinate plane.
The following is the formula for the separation between two points:
d= √(x₁-x₂)²+(y₁-y₂)²
Points (x1, Y1) and (x2, Y2)
As given in the question, the points are (-6, -6) and (-8, 2)
The distance between the two points is,
d= √(-6+8)²+(-6-2)²
d=√4+64
d=√68 units= 8.25 units
Therefore, the distance between the two points is 8.25 units

Write a system of equations with the solution (4, -3).
The system of equations with the solution (4, -3) is y = x - 7 and y = 2x - 11.
We are given a point. The coordinates of the point are (4, -3). We need to find a system of equations such that they pass through the given point.
We will use the slope-point form of a line. Let the slope of the equation of the straight line be "m". We need two equations. The general equation of a line using the slope-point form is given below.
(y - y1) = m(x - x1)
We know that both equations must pass through the given point for the solution to exist.
(y - (-3)) = m(x - 4)
(y + 3) = m(x - 4)
We just need to take any two values of the slope of the line.
First, we take m = 1. The corresponding equation is given below.
(y + 3) = m(x - 4)
(y + 3) = 1*(x - 4)
y + 3 = x - 4
y = x - 7
Next, we take m = 2. The corresponding equation is given below.
(y + 3) = m(x - 4)
(y + 3) = 2*(x - 4)
y + 3 = 2x - 8
y = 2x - 11
Hence, the system of equations is y = x - 7 and y = 2x - 11.

Mathematical induction

What do you mean by induction in mathematics?
For each and every natural number n, a statement, theorem, or formula can be proved using the mathematical induction technique. By generalizing this into the "Principle of Mathematical Induction," which we would utilize to demonstrate any mathematical assertion.
Here, n ≥ 1
1/1.2 + 1/2.3 + 1/3.4 + .............. + 1/n(n +1)
We employ the idea of Sigma here.
S/1/r(r + 1) { r = 1 to n }
Sigma [1/(r + 1) - 1/(1/r)] { r = 1 to n }
put r = 1 \s1/1 - 1/(1 + 1) = 1 - 1/2
put r = 2 \s1/2 - 1/(2 +1) = 1/2 - 1/3
put r = 3 \s1/3 - 1/(3 +1) = 1/3 - 1/4
........................................................... put r = n 1/n - 1/(n + 1)
after adding
Sigma = [1/(r+1) - 1/(1/r)] {r = 1 to n } = 1 -1/2 + 1/2 -1/3 + 1/3 - 1/4 + ............1/n - 1/(n +1)
= 1 - 1/( n +1) = n/( n +1)
Consequently, 1/1.2 + 1/2.3 + 1/3.4 +... 1/n(n + 1) = n/(n + 1).

How to determine the valuesWe have that;
Let the cost of balloons be x
Let the cost of party favors by y
From the information given, we have that;
3x + 4y = 14. 63 (1)
2x + 4y = 16. 03 (2)
Now, let's make 'x' the subject from equation (1)
x = 14. 63 - 4y/ 3 (3)
Substitute in equation (2)
3( 14. 63 - 4y/ 3) = 16. 03
expand the bracket
43. 69 - 12y /3 = 16. 03
cross multiply
43. 69 - 12y = 48. 09
collect like terms
- 12y = - 4. 4
make 'y' the subject
y = 0. 36
substitute in equation (3)
x = 14. 63 - 4(0. 36)/ 3

Based on the formula for the area of a rectangle,
L x W = 1600ft
To minimize the perimeter, of the rectangle, we must assume that:
L = W
that is L² = 1600

Michael will be spending the cost of $ 15.652 on the Furry Fabric.
Given, that Michael is dressing up as Maggie,
He is making his costume and he needs 8.6 yards of furry fabric
The fabric costs $1.82 per yard.
So, as he needs 8.6 yards of fabric and each yard of that fabric costs him $1.82.
1 yard of Furry Fabric = $1.82
8.6 yards of Furry Fabric = $1.82 × 8.6

In accordance to Thales's theorem, the geometric system has a missing side length of 15 units.
How to determine missing lengths in geometric systems by ratiosIn this problem we find a geometric system formed by two proportional trapezoids. This similarity and proportionality is defined by Thales's theorem, which states that a triangle segmented by several lines parallel to each other and parallel to the base of the figure creates triangles and quadrilaterals proportional to each other.
Then, two figures of the given trapezoids are represented by side proportionality ratios. Then, the proportionality ratio is described and its variable x is cleared within by algebra properties:
First, define the proportionality ratio associated to the geometric system:
4 / (10 + 4) = (21 - x) / 21
Second, simplify the equation and clear the variable x:
4 / 14 = 1 - x / 21
2 / 7 = 1 - x / 21
