Question

a side of the triangle below has been extended to form an exterior angle of 76°. find the value of x.
answer
attempt 1 out of 3
x =

Explanation:

Step1: Recall exterior - angle property

The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.

Step2: Set up the equation

Let the exterior angle be \(x\). The two non - adjacent interior angles are \(51^{\circ}\) and \(76^{\circ}\). So \(x=51 + 76\).

Step3: Calculate the value of \(x\)

\(x=127\).

Answer:

\(127\)
