Question

find the missing side length. assume that all intersecting sides meet at right angles. include the correct unit in your answer.

Explanation:

Step1: Analyze horizontal sides

The sum of horizontal sides on the left - hand side should equal the horizontal side on the right - hand side. The known horizontal sides on the left are 15 ft and 9 ft.

Step2: Calculate the missing horizontal side

We know that the total length of horizontal sides on the left must balance the horizontal side on the right. Let the missing side be $x$. The sum of the known horizontal sides on the left is $15 - 9=6$ ft.

Answer:

6 ft
