Question

solving for angle measures
the two labeled angles are complementary angles.
that means that their measures sum to 90°.
use the relationship you determined to write an equation to help you solve for x.
(8x - 13)°
39°

Explanation:

Step1: Recall complementary angles sum

Complementary angles sum to \(90^\circ\). The two angles are \((8x - 13)^\circ\) and \(39^\circ\).

Step2: Write the equation

Set the sum of the two angles equal to \(90^\circ\): \((8x - 13) + 39 = 90\)

Answer:

\((8x - 13) + 39 = 90\)
