Which equation would you use to solve for the value of a?


A. a + 76 = 180

B. 2a + 76 = 90

C. 2a + 76 = 180

D. 180 - 76 = a

Which equation would you use to solve for the value of a A a 76 180 B 2a 76 90 C 2a 76 180 D

Answer :

Step-by-step explanation:

Solution,

In above figure,

a+a+76°=180° (being straight angles)

2a+76°=180°

2a=180°-76°

2a=104°

a=104°/2

a=52°

Hence, I will use option c. 2a+76°=180° for calculation.
