Answer:
D
Step-by-step explanation:
First change the 1/2 to eighths. multiply numerator and denominator by 4.now subtract 4 1/8
I believe it is 50 degrees
Explanation:
180-115 = 65 degrees
Since the base angles of of an isosceles triangle are equal,
Angle C =angle A= 65 degrees
65 times 2 = 130
180-130=50
50 degrees=measure of angle B
Hope this helps
Divide the pentagon into a triangle and rectangle.
Rectangle: 12in*6in=72in^2
Triangle: (12in*5in)/2=30in^2
72in^2+30in^2=102in^2
