Question

1. the triangles are similar by the aa similarity postulate. find the value of x. 15 7.5 x 18 270 27 12 12

Explanation:

Step1: Set up proportion

Since the triangles are similar, the ratios of corresponding sides are equal. So we have $\frac{7.5}{15}=\frac{x}{18}$.

Step2: Cross - multiply

$7.5\times18 = 15\times x$, which gives $135 = 15x$.

Step3: Solve for x

Divide both sides by 15: $x=\frac{135}{15}=9$.

Answer:

9
