Question

find the missing side length. assume that all intersecting sides meet at right angles. include the correct unit in your answer. 4 yd 12 yd 11 yd 5 yd 15 yd

Explanation:

Step1: Analyze vertical side - lengths

The total vertical length on the left is 12 yd. The vertical length on the right - hand part of the figure has two segments of lengths 5 yd and the unknown length. Since all sides meet at right - angles, the sum of the vertical lengths on the right must equal the vertical length on the left.

Step2: Calculate the unknown side - length

Let the unknown side - length be $x$. We have the equation $x + 5=12$. Solving for $x$ gives $x=12 - 5$.
$x = 7$ yd

Answer:

7 yd
