Question

find the value of x.
answer attempt 1 out of 2
x =

Explanation:

Step1: Use the exterior - angle property of a triangle

The exterior - angle property of a triangle states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non - adjacent interior angles. Let the non - adjacent interior angles be \(x\) and \(116^{\circ}\), and the exterior angle be \(134^{\circ}\). So, \(134=x + 116\).

Step2: Solve for \(x\)

Subtract \(116\) from both sides of the equation \(134=x + 116\).
\(x=134 - 116\)
\(x = 18\)

Answer:

\(x = 18\)
