Answer:

x = 25

Step-by-step explanation:

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

$\frac{BQ}{QD}$ = $\frac{RC}{CD}$ , substitute values

$\frac{24}{40}$ = $\frac{15}{x}$ ( cross- multiply )

24x = 600 ( divide both sides by 24 )

x = 25
