Question

architecture in an a - frame house, the roof extends to the ground level. if each side of the roof meets the ground at a 60° angle, what will be the measure of the angle where the two sides of the roof meet? the angle measure will be

Explanation:

Step1: Recall the sum of angles in a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\).

Step2: Subtract the known angles

We know two angles are \(60^{\circ}\) each. Let the unknown angle be \(x\). Then \(x = 180^{\circ}-60^{\circ}-60^{\circ}\).

Answer:

\(60\)
