Question

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 2 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

We know that \(76^{\circ}=x + 51^{\circ}\).

Step3: Solve for \(x\)

Subtract \(51^{\circ}\) from both sides of the equation: \(x=76^{\circ}-51^{\circ}\).

Answer:

\(25^{\circ}\)
