For safety reasons, a ladder should make a 15β angle with a wall. Is the ladder shown leaning at a safe angle? Explain. The space between the ladder and the wall is a triangle, and the sum of all of the angles inside a triangle is 180β. The angle created by the ground and the wall is β. Because a straight angle is β, the acute angle created by the ladder and the ground is β. Since the sum of the three angles inside the triangle is 180β, the angle formed by the ladder and the wall is β which a safe angle. 9 of 10 answered need help?Check answer Next
