Answer:
x = [tex]\frac{170}{19}[/tex] = [tex]8\frac{18}{19}[/tex] ≈ 8.94736842
Step-by-step 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 = [tex]\frac{170}{19}[/tex] = [tex]8\frac{18}{19}[/tex] ≈ 8.94736842
