Question

a side of the triangle below has been extended to form an exterior angle of 124°. find the value of x. answer attempt 1 out of 3 x = submit answer

Explanation:

Step1: Use the linear - pair relationship

The sum of an interior angle and its adjacent exterior angle is \(180^{\circ}\). So, \(x + 124=180\).

Step2: Solve for \(x\)

Subtract \(124\) from both sides of the equation: \(x=180 - 124\).

Answer:

\(x = 56\)
