Question

the two angles are supplementary if a=19x+3 and b= 21x +17 solve for x and find the measure of each angle

Answer 1

x = 4

a = 79

b = 101

Explanation:

Supplementary means equal to 180° after all angles are added together.

a=19x+3

b= 21x +17

(19x+3) + (21x +17) = 180

19x + 3 + 21x + 17 = 180

40x + 20 = 180

40x = 160

x = 4

a = 19(4)+3 = 79

b = 21(4) +17 = 101
