Question

drawing not to scale 124° 112° 62° 68°

Explanation:

Step1: Identify the triangle type

The triangle is isosceles (two equal sides), so the base - angles are equal.

Step2: Use the angle - sum property of a triangle

The sum of angles in a triangle is \(180^{\circ}\). Let the two equal base - angles be \(56^{\circ}\) each. Then \(x + 56+56=180\).

Step3: Solve for \(x\)

\(x=180-(56 + 56)\)
\(x = 180 - 112\)
\(x=68\)

Answer:

\(68^{\circ}\)
