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

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

Take any two sides and then equate them

@LovelyMegan did you understand Parth's explanation?

Explain more plz

is it the same formula?

Parth (parthkohli):

x + 12 = 2x - 5 Solve this

Parth (parthkohli):

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

Parth (parthkohli):

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

@LovelyMegan have you tried any of these formulas yet?

which formula am i use n ?

6 years ago
OpenStudy (anonymous):

either?

OpenStudy (turingtest):

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

OpenStudy (anonymous):

ok

6 years ago
OpenStudy (anonymous):

so im solve n for x?

6 years ago
OpenStudy (turingtest):

yep

6 years ago
OpenStudy (turingtest):

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

6 years ago
OpenStudy (anonymous):

wait but what is x

6 years ago
OpenStudy (turingtest):

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

6 years ago
Parth (parthkohli):

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

6 years ago
Parth (parthkohli):

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

OpenStudy (anonymous):

Uhhh im not getting any of these answer

6 years ago
OpenStudy (turingtest):

ok, which equation did you use?

6 years ago
OpenStudy (anonymous):

3x-22=x+12

6 years ago
OpenStudy (turingtest):

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