Question

a side of the triangle below has been extended to form an exterior angle of 118°. find the value of x.

Explanation:

Step1: Use the exterior angle property

The sum of an interior angle and its adjacent exterior angle is \(180^{\circ}\). So \(x + 118=180\).

Step2: Solve for \(x\)

Subtract \(118\) from both sides: \(x=180 - 118\).

Answer:

\(x = 62\)
