Answer:
x = 22.5°
Step-by-step explanation:
The interior angle at E is (180 -4x), the supplement of the exterior angle there, 4x. The sum of angles 2x and (180-4x) will be equal to 6x, because alternate interior angles at transversal BE are congruent:
2x +(180 -4x) = 6x
180 = 8x . . . . . . . add 2x and simplify
22.5 = x . . . . . . . divide by 8
The value of x is 22.5°.

The quilt made by Spencer had a 7×7 array of different color square patches such that each patch is 
in long.
To find: the area of the whole quilt
Solution:
Side of each quilt = 
Quilt is in the form of a square such that area of square is given by 
Therefore, area of quilt = 
square inches
A is 40
B is 50
C is 115
Explanation, A is the same as the opposite, A + B + 90 = 180, and C + 65 = 180
