Question

Suppose an equilateral triangle has sides given by
3y - 4
5y - 18
2y + 3

What is the length of each side of the triangle?

Answer 1

also can you explain how to do this please?

Answer 2

do you know the definition of equilateral triangle?

Answer 3

yeah all sides are equal

Answer 4

so just set the expression for one side equal to another.

Answer 5

im not getting you bro?? how would i do that? You don't have to give me the answer i jus need you to walk me thru it..

Answer 6

i am. you have an expression for each side.
Side 1 = 3y-4
Side 2 = 5y-18
Side 3 = 2y+3

Set one side equal to another. So set side 1 = side 2
OR
side 2= side3
OR side 1 = side 3

Answer 7

lol im sorry but how would i ''set'' the sides?

Answer 8

He's saying since it an equalateral triangle all the sides will be the same so:

3y-4=5y-18=2y+3

So the length of the side could be solved using any one of those.

2y+3=0
2y=-3
y=2/3 since a length can never be negative.

Do that for all three (the two remaining) equations and you have the lengths of all the sides.

Answer 9

thank you!
