Question

1. Angles measuring 8x – 3 and 7x + 18 are supplementary. Find the measure of each angle. (5 points)​

Answer 1

85º and 95º

Explanation:

supplementary angle total 180

(8x – 3) + (7x + 18) = 180

Combine like terms

15x + 15 = 180

15x = 165

x = 11

---------------------

8x – 3

8(11) - 3

88 - 3

85º

7x + 18

7(11) + 18

77 + 18

95º
