Question

Can someone teach me step by step

Answer 1

x = 25

Explanation:

Since CQ is parallel to BR and intersects the other 2 sides then it divides those 2 sides proportionally, that is

`(BQ)/(QD)` =
`(RC)/(CD)` , substitute values

`(24)/(40)` =
`(15)/(x)` ( cross- multiply )

24x = 600 ( divide both sides by 24 )

x = 25
