Question

∠6 and ∠7 form a linear pair. Twice the measure of ∠6 is twelve more than four times the measure of ∠7. Find the measure of each angle.

Answer 1

Answer:

   ∠7= 58  ∠6=122

Step-by-step explanation:

∠6 and ∠7 form a linear pair

Therefore ∠6+∠7=180

And 2∠6= 4∠7+12

              2∠7-∠6=-6

Adding both the equation

           3∠7 =174

            ∠7= 58

∠6= 116+6=122
