So, try to use that..

anonymous · Answer

problem is that i don't remember anything about it..

anonymous · Answer

Oh..
Pythagorean Theorem says that:

In right angled triangled, if you have two sides and a hypotenuse,

then :

$$(hypotenuse)^2 = (first \; \; side)^2 + (second \; \; side)^2$$

anonymous · Answer

so is this case, what would "l" be?

anonymous · Answer

"l" is your first or second side, you can take what you want..

Hypotenuse = n

First side = m

Second Side = l

anonymous · Answer

"l" is your one of the sides..

anonymous · Answer

Try to use that..

anonymous · Answer

Using Pythagoras Theorem:

$$n^2 = l^2 + m^2$$

anonymous · Answer

You are given with m and n values..

Try to find "l" here..
