Question

what is the missing angle in the triangle?

Explanation:

Step1: Recall angle - sum property

The sum of the interior angles of a triangle is 180°.

Step2: Let the missing angle be \(x\)

We know two angles are 10° and 70°. So, \(x + 10^{\circ}+70^{\circ}=180^{\circ}\).

Step3: Solve for \(x\)

\(x=180^{\circ}-(10^{\circ} + 70^{\circ})=100^{\circ}\)

Answer:

100°
