Question

In parallelogram ABCD, m∠A = 6x + 12 and m∠B = 3x + 6. What is the value of x? I think it's 18, I'm not sure.

Answer 1

Answer:

yes you are right

x=18

Step-by-step explanation:

in parallelogram all opposite side and angle are equal.

then sum of 2 angle in parallelogram=180

m∠A+m∠B=180

6x+12+3x+6 = 180

9x+18=180

9x=180-18

9x=162

x=18
