Question

Find the value of Z for the triangles

Answer 1

z = 17.5

Explanation:

segment RX is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

`(RS)/(RT)` =
`(SX)/(TX)` , substitute values

`(15)/(z)` =
`(6)/(7)` ( cross- multiply )

6z = 105 ( divide both sides by 6 )

z = 17.5
