Question

which equation can you use to find the value of x? x = 120 + 35 x = 120 - 35 x + 120 + 35 = 180 x + 120 - 35 = 180

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°.

Step2: Identify the angles in the triangle

The three angles of the triangle are \(x\), 120°, and 35°.

Step3: Set up the equation

Based on the angle - sum property, \(x + 120+35 = 180\).

Answer:

\(x + 120 + 35=180\)
