Question

Hypotenuse of a right triangles whose legs are square root of 10 and sqare root of 15

Answer 1

Sqrt{10}² + sqrt15² = c²

The square of any square root is that number without the square root sign

So now we have 10 + 15= c²
                            25     = c²
                     So c= 5

Answer 2

10^2 + 15^2 = c^2 

100 + 225 = c^2 

325 = c^2 

Find the square root of both sides .... 

18.02 = c = hypotenuse.
