Question

if angle 1 and angle 2 form a linear pair. if m angle 1=(5x+9) and m angle 2= (3x+11), find the measure of each angle

Answer 1

5x+9 = 109

3x+11 =71

Explanation:

A linear pair adds to 180

5x+9 + 3x+11 =180

Combine like terms

8x + 20 =180

Subtract 20 from each side

8x +20-20 = 180-20

8x = 160

Divide each side by 8

8x/8 = 160/8

x=20

5x+9 = 5*20+9 = 100+9 = 109

3x+11 = 3*20+11 = 60+11=71
