Answer 1

A triangle's sides are suppose to add up to 360 degrees. So create a alegbraic equation with x as the variable. So the equation should add up to 720 degrees for two triangles.

720 = 15x - 3 + 56

720 = 15x + 53

667 = 15x

x = 44.5 (rounded to tenth)

Tell me if I'm incorrect.

Answer 2

x = 3

Explanation:

The line segment is an angle bisector thus the following ratios are equal

`(32)/(24)` =
`(6x+6)/(9x-9)`, that is

`(4)/(3)` =
`(6x+6)/(9x-9)` ( cross- multiply )

4(9x - 9) = 3(6x + 6) ← distribute parenthesis on both sides

36x - 36 = 18x + 18 ( subtract 18x from both sides )

18x - 36 = 18 ( add 36 to both sides )

18x = 54 ( divide both sides by 18 )

x = 3
