Question

Solve for x.
112°
(5x - 3)°
(4x + 16)°

Answer 1

To find x add the two interior angles together and put them equal to 112 (the exterior angle).

ANSWER: 109/9

Answer 2

11

Explanation:

180 - 112 = 68

4x + 16 +5x - 3 + 68 = 180

simplify.

9x + 81 = 180. subtract 81 from 180

9x = 99. divide 99 by 9

x = 11.
