Question

when the hypotenuse is 11.1 and one leg of the right triangle is 7.2 whats the other leg?

Answer 1

what does the pythag thrm give us?

Answer 2

Okay so. The pythagorean theorem tells us that \[a^2+b^2=c^2\].

Let's substitute the numbers. Let:
a=7.2
b=x
c=11.1
Now substitute these numbers into the equation!
\[7.2^2+x^2=11.1^2\]
\[x^2=11.1^2-7.2^2\]
Now just solve that equation! :)
