Question

a side of the triangle below has been extended to form an exterior angle of 74°. find the value of x.
answer attempt 1 out of 2
x =

Explanation:

Step1: Use the exterior angle theorem

The exterior angle theorem states that an exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.
So, \(x + 24=74\)

Step2: Solve for \(x\)

Subtract 24 from both sides of the equation: \(x=74 - 24\)

Answer:

\(50\)
