I’d really appreciate some help :)

Answer/Step-by-step explanation:

The corresponding side lengths of two triangles are always equal. Apply this in solving for x

4.

Cross multiply

6x = 45

divide both sides by 6

y = 7.5

5.

Cross multiply

8x = 110

divide both sides by 8

x = 13.75

6.

Cross multiply

7x = 48

divide both sides by 7

x = 6.86 (nearest hundredth)

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

no
