Question

1. the following two triangles are similar. find x. 7 6 5

Explanation:

Step1: Set up proportion

Since the triangles are similar, the ratios of corresponding sides are equal. So, \(\frac{9}{45}=\frac{x}{25}\).

Step2: Cross - multiply

Cross - multiplying gives \(45x = 9\times25\).

Step3: Solve for \(x\)

First, calculate \(9\times25 = 225\). Then, \(x=\frac{225}{45}\).

Answer:

\(x = 5\)
