Question

The three sides of an equilateral triangle measure x + 12, 2x - 5 and 3x - 22 inches. The sides of the triangle measure
17 inches
29 inches
32.5 inches
44.5 inches

Answer 1

Equilateral triangle means that all sides are equal. We can do the same thing in this.
Just put up an equation.

Answer 2

Take any two sides and then equate them

Answer 3

@LovelyMegan did you understand Parth's explanation?

Answer 4

Explain more plz

Answer 5

is it the same formula?

Answer 6

x + 12 = 2x - 5
Solve this

Answer 7

Alternatively, you can do this too, since they're all equal.
2x - 5 = 3x - 22

Answer 8

Or even this.
3x - 22 = x + 12

Answer 9

@LovelyMegan have you tried any of these formulas yet?

Answer 10

just about to i had to take a quick break

Answer 11

well please let me know if/where you get stuck in solving this problem :)

Answer 12

which formula am i use n ?

Answer 13

either?

Answer 14

any one of the three Parth gave you; they all give the same answer.

Why? Because the triangle is \(equilateral\) which means all sides have the same length, so we can set any two equal to solve for x

Answer 15

ok

Answer 16

so im solve n for x?

Answer 17

yep

Answer 18

then you need to plug that value of x into any one of the expressions for the length of the side to get the actual answer

Answer 19

wait but what is x

Answer 20

that's your job: to find x with any of the three formulas parth gave you

Answer 21

x is just a variable. When you find x, then plug it in.

Answer 22

Make sure that when you plug-in, you get all of them the same.

Answer 23

Uhhh im not getting any of these answer

Answer 24

ok, which equation did you use?

Answer 25

3x-22=x+12

Answer 26

can you show me how you worked it?
what you got for x ?

Answer 27

see /7 now im suck
