Question

find the value of x.
triangle with angles 31°, 89°, and x°

Explanation:

Step1: Recall triangle angle sum

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

Step2: Set up the equation

Let the angles be \(31^\circ\), \(89^\circ\), and \(x^\circ\). So, \(31 + 89 + x = 180\).

Step3: Solve for x

First, calculate \(31 + 89 = 120\). Then, \(x = 180 - 120 = 60\).

Answer:

\(60\)
