Question

Which equation can be used to solve for x in the parallelogram below?


A) 3x-12=6x+12

B) (7x-8)+(6x+12)=90

C) 3x-12=2x+8

D) (7x-8)+(6x+12)=180

Answer 1

Answer:

B. (3x - 12)° = (2x + 8)°

Step-by-step explanation:

This equation can be used to solve x.

3x - 12 = 2x + 8

3x - 2x = 12 + 8

x = 20°

-------------------------------------------------------------------

Verification:

3(20) - 12 = 2(20) + 8

60 - 12 = 40 + 8

48° = 48°
