Question

find the value of x 125 54 answer additional solution no solution

Explanation:

Step1: Find adjacent interior angle

The exterior angle is \(125^\circ\), so the adjacent interior angle is \(180 - 125 = 55^\circ\) (linear pair).

Step2: Sum of triangle angles

In a triangle, sum of angles is \(180^\circ\). Let the unknown angle be \(x\). So \(x + 55 + 54 = 180\).

Step3: Solve for \(x\)

Simplify: \(x + 109 = 180\). Then \(x = 180 - 109 = 71\).

Answer:

\(71\)
