A certain triangle has a perimeter of 3071 m. The shortest side measures 78 mi less than the middle side, and the longest side measures 377 mi more than the middle side. Find the lengths of the three sides,

x/3-10=8

x/3=18

x=48

answer: i guess 105 degrees?

step-by-step explanation:

step-by-step explanation:

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
