Find the lengths of the sides of a triangles with vertices: (0,0), (5,0), (5,12)

OpenStudy (anonymous):

do you have any ideas?

OpenStudy (anonymous):

5,12,12

OpenStudy (anonymous):

how is the last 12?

OpenStudy (anonymous):

5,5,12

OpenStudy (anonymous):

|dw:1389990072858:dw| comes up a bit short1

OpenStudy (anonymous):

what kind of triangle is it?

OpenStudy (anonymous):

right

OpenStudy (anonymous):

yep so what can you use?

OpenStudy (anonymous):

Use the pythagorean theorem to find the hypotonuse a*a+b*b=c*c

OpenStudy (anonymous):

not asking you, @Thisisisntme , trying to help @Sarah_Miller720 learn. but thanks anyway.

OpenStudy (anonymous):

how would i solve this?

OpenStudy (anonymous):

take the square root of what you get from a*a + b*b

OpenStudy (anonymous):

|dw:1389990384036:dw| \(a^2+b^2=c^2\) to solve for one of the variables, simply isolate it and then take the square root of both sides. rememeber, c is always the side opposite the right angle.

OpenStudy (anonymous):

Im confused :/

OpenStudy (anonymous):

|dw:1389991224714:dw| \[c=\sqrt{a^2+b^2}\]
