Question

How do you use pythagorean theorem to solve the right triangle if the legs have lengths 4 and 9?

Answer 1

In this case consider the triangle to be standing on 2 legs.

Answer 2

The equation for a right triangle is `c^2=a^2+b^2`.

Let `a=9 and b=4`.

`c=sqrt(a^2+b^2)`

`c=sqrt(9^2+4^2)`

`c=sqrt(81+16)=sqrt(97)`
