Question

the figures are similar. find the missing side and enter in the pink box. 15.3 21.3 5.1 x

Explanation:

Step1: Set up the proportion

Since the figures are similar, the ratios of corresponding sides are equal. So, \(\frac{15.3}{5.1}=\frac{21.3}{x}\).

Step2: Cross - multiply

\(15.3x = 5.1\times21.3\).

Step3: Solve for \(x\)

First, calculate \(5.1\times21.3 = 108.63\). Then \(x=\frac{108.63}{15.3}\).
\(x = 7.1\).

Answer:

\(7.1\)
