Question

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

Explanation:

Step1: Recall linear pair property

A linear pair of angles sums to \(180^\circ\). So, \(x + 118 = 180\).

Step2: Solve for \(x\)

Subtract \(118\) from both sides: \(x = 180 - 118\).
\(x = 62\).

Answer:

\(x = 62\)
