Question

a side of the triangle below has been extended to form an exterior angle of 71°. find the value of x.
answer attempt 1 out of 2
x =

Explanation:

Step1: Apply 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, \(x + 46=71\).

Step2: Solve for \(x\)

Subtract 46 from both sides of the equation \(x + 46=71\).
\(x=71 - 46\).

Answer:

\(25\)
