Question

a side of the triangle below has been extended to form an exterior angle of 66°. find the valbe 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, \(x + 18=66\).

Step2: Solve for \(x\)

Subtract 18 from both sides of the equation: \(x=66 - 18\).

Answer:

\(x = 48\)
