The measurement of all four angles is 105°
What is an angle?
When two solid lines or rays intersect at a single endpoint, an angle is created. The vertex about an angle is the location where two points come together.Vertex: The intersection of two lines or sides at an angle is called a vertex. In the diagram, O is the vertex.Arms: The angle's two sides are linked at a single end. The arms of just an angle are OA and OB.180° [Linear pair with angles] = m1 + 75°
The opposite angles of either a rectangle are equal: m1 = 180° - 75° = 105° m2 = m1.
[Vertically opposing angles] m2 = m1 = 105° m2 = m3 = 105°
m∠3 = m∠4 = 105° Coordinating angles
As a result, the measurement of all four angles is 105°.

What are triangles?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.So, the area of the triangle:
The formula for the area of the triangle: 1/2|x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂)|
Now, insert the values in the formula as follows

We have to explain what is scalar factor and scalar drawing.
What is a scalar factor?
To adjust the size of a figure without altering its shape, a scalar factor is a number or conversion factor that is utilized. It is employed to change the size of an object. If the original figure's dimensions and the dilated (increased or lowered) figure's dimensions are known, the scalar factor can be determined.
The original rectangle's dimensions in the accompanying figure are 3 units and 2 units. The formula: Dimensions of the new shape = Dimensions of the old shape Scalar factor is used to multiply the dimensions by the scalar factor of 3 to produce an expanded figure. The revised dimensions are thus given as 9 units and 6 units, respectively. In a similar manner, we multiply the original dimensions by a scalar factor of half to produce a reduced figure. As a result, the reduced dimensions are given as 1.5 units and 1.
What is a scalar drawing?
An accurate portrayal of an object or location in two dimensions is called a scalar drawing. Scalar drawings include, but are not limited to, maps and floor plans.
The scalar describes the actual length that each length on the scalar graphic corresponds to.
A scalar of "1 inch to 5 miles," for instance, indicates that 1 inch on the figure corresponds to 5 actual miles. If a road is depicted on a drawing as being 2 inches long, it is actually 10 miles long.

Claire is building a rectangular frame to hold her stretched canvas painting. she has 14
feet of wood to build the frame. what is the maximum possible area for the painting?
The maximum possible area for the rectangular painting is 12.25 square feet.
A crossed rectangle is a quadrilateral that is formed by the two diagonals, two opposed sides, and two opposite corners of a rectangle (therefore only two sides are parallel).
It is a special illustration of an antiparallelogram in which the angles are not all right angles and equal, despite the fact that opposite angles are equal. There are so-called rectangles with opposite sides of equal length and equal angles that aren't right angles in other geometries, such as spherical, elliptic, and hyperbolic ones.Let the length of the painting be x and the width be y.
perimeter of rectangle = 2( x + y )
or,2( x + y ) = 14
or, x+y = 7
or, y = 7-x
Area of the painting in the form of a function
A(x) = x (7 - x)
A(x) = 7x - x²
Now we find the first differentiation of A(x).
A'(x) = 7 -2x
now , A'(x) = 0
or, x = 7 / 2 = 3.5
Area of the frame = 3.5² = 12.25 square feet.

Lucia ordered a set of beads. She received 35 beads in all. 7 of the beads were green. What percentage of the beads were green?
Write your answer using a percent sign (%).
The percentage of the beads were green is 20% .
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.
Given that
Total number of beads = 35
In which Number of green beads = 7
Find out What percentage of the beads were green?
By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.
So here total value = 35
Value = 7
Put the values in the formula
(value/total value)100%
= (7/35) × 100 %
= 1/5 × 100 %
= 100 / 5 %
= 20 %
