For Question 5, X=7.5

Step-by-step explanation:

This triangle is bisected by an altitude. This proves that the triangle is cut in half. Because the bisected base lengths are equal, we know that 2x=15. Divide 15 by 2 to get 7.5 .

ik how do do this just give me a few minutes and i will give it to

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
