Here we use the property, angles opposite to equal sides are equal,
(5x+27)=(45+3x)
5x-3x=45-27
2x =18
x=18/2
x=9
Answer is D. x=9

Answer:
5 in.
Step-by-step explanation:
Given that
b1 = 12
b2 = 8
A = 50
Formula is (1/2)h(b1 + b2), on substituting
50 = 1/2 * h(12 + 8)
50 = 1/2 * h(20)
100 = 20h
h = 100/20
h = 5
The height is 5 in
