Question

find the length of a third side of a right triangle

Answer 1

The sides of a right triangle can be found using the Pythagorean Theorem: a^2+b^2=c^2

c is the hypotenuse (the longest side) of the right triangle and a and b are the two other legs. Knowing any two sides of the right triangle, you can find the other using this formula.

Hope this helps!

Answer 2

you will need to use the pythagorean theorem

a^2 +b^2 = c^2

where a and b are the sides of the right triangle and c is the hypotenuse
