Question

the two labeled angles are adjacent angles. that means that their measures sum to 69°. use the relationship you determined to write an equation to help you solve for x.

Explanation:

Step1: Identify the angles

The two adjacent angles are \((7x)^\circ\) and \((9x - 3)^\circ\), and their sum is \(69^\circ\).

Step2: Write the equation

To form the equation, we add the two angle expressions and set them equal to \(69\). So the equation is \(7x+(9x - 3)=69\).

Answer:

\(7x+(9x - 3)=69\)
