Step by step answers

Answer 1

x =
`(170)/(19)` =
`8(18)/(19)` ≈ 8.94736842

Explanation:

By the same side exterior angles theorem, (9x - 5) + (10x - 5) = 180.

We can use (9x - 5) + (10x - 5) = 180 to find x.

(9x - 5) + (10x - 5) = 180

get rid of the parentheses.

9x - 5 + 10x - 5 = 180

simplify

19x - 10 = 180

-10 both sides

19x = 170

÷19 both sides

x = 170÷19

simplify

x =
`(170)/(19)` =
`8(18)/(19)` ≈ 8.94736842
