Question

a side of the triangle below has been extended to form an exterior angle of 162°. find of x. answer attempt 1 out of 3 x =

Explanation:

Step1: Recall exterior - angle property

The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles. So, \(x + 54^{\circ}=162^{\circ}\).

Step2: Solve for \(x\)

Subtract \(54^{\circ}\) from both sides of the equation: \(x=162^{\circ}- 54^{\circ}\).

Answer:

\(108^{\circ}\)
