Question

A right triangle has one side of length 7 and a hypotenuse of length 10. How long is the third side of the triangle?

Answer 1

a^2+b^2=c^2
pythagorean's theorem, plug and chug

Answer 2

can you do the rest?

Answer 3

Oh I get it! I think

Answer 4

So like 7^2+10^2 = c^2?

Answer 5

alright, the equation is 10^2=7^2+b^2
incase you need to check your work
100 = 49 +b^2
b^2 = 51
b = sqrt(51)

Answer 6

c has to be hypotenuse, a and b are the adjacent/opposite sides of the right triangle

Answer 7

Oh and all I have to do is square root 51?

Answer 8

yep, do you see how i arrived at it though?

Answer 9

Yeah I think so. Since a and b are adjacent sides and c is the hypotenuse you just plug in what you already have which is a and c

Answer 10

you got it

Answer 11

and the rest of it works out

Answer 12

Thank you! :D
