Find the length of the unknown side of the right triangle with sides​ a, b, and​ c, where c is the hypotenuse. aequals=2​, bequals=3

Question

i need help with this math test that is very challenging

Answer 1

c² = a² + b² for right triangles, as I am sure you've been told.

 

The sum of the squares of the two legs (a &b) is 4+9 = 13.

So hypotenuse c = square root of 13.

 

It's very important that you study this because stuff like this happens ALL THE TIME in all mathematics!
