Answer:

9

Explanation:

The ratio of 5 to 5+3 is equivalent to the ratio of 15 to 15+x. This is because when you have a triangle inside of a triangle and both of them share two of the same sides and the third sides are parallel to each other, the side ratios of the triangles are always proportionate.


(5)/(5+3) =(15)/(15+x) Starting equation


(5)/(8) =(15)/(15+x) Simplify


5(15+x)=8*(15) Cross multiply


75+5x=120 Distributive Property on left and simplify on right


5x=45 Isolate the variable


x=9 Divide both sides by 5 (Division Property of Equality)
