David's construction company is designing roof trusses in the shape of isosceles triangles for new homes in Orlando. The pitch of the room can be determined by finding the angle between the run and the slope of the roof. What is the pitch of the roof to the nearest degree?

question:

could we have options?

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

part a: 1.08

part b: 27.59
