Question

1. find the value of x to represent an exterior angle of the triangle. x = degrees

Explanation:

Step1: Recall exterior - angle property

The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.

Step2: Set up the equation

Let the two non - adjacent interior angles be 50° and 70°. Then \(x=50 + 70\).

Step3: Calculate the value of x

\(x = 120\).

Answer:

120 degrees
