Question

use the triangle shown below to answer the following questions. write an equation that can be solved to find the measure of the missing angle. note: do not solve the equation yet. 63° 64° x°

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\).

Step2: Set up the equation

Add the three angles (\(63^\circ\), \(64^\circ\), and \(x^\circ\)) and set equal to \(180^\circ\). So the equation is \(63 + 64 + x = 180\).

Answer:

\(63 + 64 + x = 180\)
