Question

a side of the triangle below has been extended to form an exterior angle of 126°. find the value of x.
answer attempt 1 out of 2
x =

Explanation:

Step1: Use the exterior angle property

The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles. So, \(126^{\circ}=23^{\circ}+x^{\circ}\).

Step2: Solve for \(x\)

Subtract \(23^{\circ}\) from both sides of the equation: \(x = 126 - 23\).

Answer:

\(x = 103\)
