Question

find the value of x. x = ?° 40° 70°

Explanation:

Step1: Use the triangle angle sum theorem

The sum of angles in a triangle is \(180^{\circ}\). So, \(x + 40^{\circ}+70^{\circ}=180^{\circ}\).

Step2: Solve for \(x\)

\(x=180^{\circ}-(40^{\circ} + 70^{\circ})\)
\(x=180^{\circ}-110^{\circ}\)

Answer:

\(70\)
