You make a scale drawing of a banner for a school dance. You use a scale of 1 inch = 3 feet. What is the actual width of the banner?

width x 3 = actual width

Step-by-step explanation:

If we use the scale then lets say we want a banner that is 20 inches, so we would use that scale and multiply 20 by 3 and we would get 60 so the actual width of the banner would be 60 feet

439 is the answer

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
