7x + 4 = 12
7x = 12-4
7x = 8
x = 7/8
Step-by-step explanation:
ur answer is there in image
C. 72 sorry if its wrong
trapezoid formula : A= 1/2h(B+b)
plug in:
A= 1/2×6(10+14)
A= 3(24)
A= 72
∠B = 60°
They are supplementary angles, which means they add up to 180°.
∠B + ∠A = 180
? + 120 = 180
? = 180 - 120
? = 60°
