2. if ∠a and ∠b are supplementary and ∠a = 4x – 8 and ∠b = 2x +2, what is the value of x? a. 43 b. 22 c. 180 d. 31

The value of x is 31 .

Option (D) is correct .

Step-by-step explanation:

As given

If ∠A and ∠B are supplementary and ∠A = 4x – 8 and ∠B = 2x +2 .

Thus

∠A + ∠B = 180 °

4x - 8 + 2x+ 2 = 180

6x - 6 = 180

6x = 180 + 6

6x = 186

x = 31

Therefore the value of x is 31 .

Option (D) is correct .
