Question

the figures are similar. find the missing side and enter in the pink box.
x
82.8
7.7
9.2

Explanation:

Step1: Set up proportion

Since the figures are similar, the ratios of corresponding sides are equal. So, \(\frac{x}{7.7}=\frac{82.8}{9.2}\).

Step2: Solve for \(x\)

Cross - multiply: \(9.2x = 7.7\times82.8\). Then \(x=\frac{7.7\times82.8}{9.2}\). Calculate \(7.7\times82.8 = 637.56\), and \(637.56\div9.2 = 69.3\).

Answer:

\(69.3\)
