We have a right triangle with a missing side.

When we have two sides given sides on the right triangle and we need to find the missing side, we use the Pythagoras theorem:

The formula is given by:


a^2=b^2+c^2

Where:

a = Hypotenuse

b= Opposite side

c= Adjacent side

Now, we need to label the sides of the given triangle:

The largest side, represents the hypotenuse, in this case, a=15m.

The adjacent side is between the 90 degrees angle and the hypotenuse, in this case, c = 9m

Therefore, the missing side is the opposite side, let set b for this side:

Replacing these values:


(15m)^2=b^2+(9m)^2
225=b^2+81

Solve the equation for b:


225-81=b^2
144=b^2
\sqrt[]{144}=\sqrt[]{b^2}

Therefore, the missing side:


12=b
