Question

which equation can be used to find the value of z? z = 80 + 30 z + 80 + 30 = 180 z + 80 + 30 = 360 z = 80 - 30

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180 degrees. In the given triangle, the three interior angles are \(z\), 80 degrees, and 30 degrees.

Step2: Set up the equation

Based on the angle - sum property, we have the equation \(z + 80+30 = 180\).

Answer:

\(z + 80 + 30=180\)
