Question

question 4 solve for a. 25 10x 2y 4y

Explanation:

Step1: Assume similar - triangles

If the two triangles are similar, the ratios of their corresponding sides are equal.

Step2: Set up proportion

Let's assume the triangles are similar. The ratio of the horizontal sides is $\frac{8x}{2x}=4$. So the ratio of the vertical sides should also be 4. If the vertical side of the smaller triangle is $y$, then the vertical side of the larger triangle $A = 4y$.

Answer:

D. 4y
