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

use Pythagorus theorem. Do you know its formula?

Answer 2

nope can you give it to me please

Answer 3

Let c be the hypotenuse.
\[c^2=a^2+b^2\]
now, substitute c=10 and a=7

\[10^2=7^2+b^2\]
\[100-49=b^2\]
\[\sqrt51=b\]

Answer 4

your length would be \[\sqrt{51}\] . Depending on your answer, you might want to simplify it further.
