Answer 7

Oh..
Pythagorean Theorem says that:

In right angled triangled, if you have two sides and a hypotenuse,

then :

\[(hypotenuse)^2 = (first \; \; side)^2 + (second \; \; side)^2\]

Answer 8

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

Answer 9

"l" is your first or second side, you can take what you want..

Hypotenuse = n

First side = m

Second Side = l

Answer 10

"l" is your one of the sides..

Answer 11

Try to use that..

Answer 12

Using Pythagoras Theorem:

\[n^2 = l^2 + m^2\]

Answer 13

You are given with m and n values..

Try to find "l" here..
