Question

a side of the triangle below has been extended to form an exterior angle of 163°. 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 of a triangle is equal to the sum of the two non - adjacent interior angles. So, \(163^{\circ}=x^{\circ}+51^{\circ}\).

Step2: Solve for \(x\)

Subtract \(51^{\circ}\) from both sides of the equation: \(x = 163 - 51\).

Answer:

\(x = 112\)
