Question

If a and b are two sides of a right triangle, find the length of the hypotenuse, c.

a=8, b=4, c=?

Answer 1

you need to use the pythagorean theorem for this ..a^2 + b^2 = c^2 ..can you do that?

Answer 2

can u work me through it please

Answer 3

a squared + b squared = c squared

so..

8x8 + 4x4
64 + 16 = 80
c= root of 80
so answer is \[c=\sqrt{80}\]
