Question

Find the value of x.
A 15.0
B. 13.5
C. 9.0
D. 7.5

Answer 1

D

Explanation:

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

`(x)/(7)` =
`(15)/(14)` ( cross- multiply )

14x = 105 ( divide both sides by 14 )

x = 7.5 → D
