The sum of three numbers is 35. The first number is three less than the second and the third is two more than four times the second. What are the numbers?

The first is 3

The second is 6

The third is 26

Step-by-step explanation:

x + y + z = 35

x = y - 3

z = 4y + 2

(y - 3) + y + (4y + 2) = 35

6y - 1 = 35

6y = 36

y = 36/6

y=6

x = y - 3

x = 6 - 3

x = 3

z= 4y + 2

z = (4 x 6) + 2

z = 26

7

step-by-step explanation:

the answer would be 7

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
