Question

find the missing length in the diagram.
13 in.
5 in.
10 in.
6 in.
?
2 in.

Explanation:

Step1: Analyze the length relationship

The total length of the top side is \(13\) inches. It is composed of \(6\) inches, the unknown length (\(x\)), and \(2\) inches.

Step2: Set up the equation

We can write the equation \(6 + x+ 2=13\).

Step3: Solve the equation

First, simplify the left - hand side of the equation: \(x + 8=13\). Then, subtract \(8\) from both sides of the equation: \(x=13 - 8\).

Answer:

\(5\) inches
