Question

Two angles are same-side interior angles. The measures of the angles are represented by the expressions 7x+18 and 10x+9.

What are the two angle measures?

Answer 1

Answer:

See answer below.

Step-by-step explanation:

Same-side interior angles = 180°

(7x + 18) + (10x + 9) = 180

17x + 27 = 180

17x = 153

x = 153/17 = 9

one angle = 7(9) + 18 =81

the other angle = 10(9) + 9 = 99
