Question

I will give you 20 points IF THE ANSWER IS CORRECT
angle 3 and angle 4 are supplementary. m<3=7x-3 and m<4=2x+12. Find the measure of each angle

Answer 1

Step-by-step explanation:

Sum of supplementary angle = 180⁰

2x + 12 + 7x - 3 = 180

9x + 9 = 180

9x = 180 - 7

9x = 171

x = 171/9

x = 19

m<3 = 7(19) - 3 = 133 - 3 = 130⁰

m<4 = 2(19) + 12 = 50⁰
