Question

What is the length of the hypotenuse of a right triangle if the two other sides are of lengths 12 and 10?

Answer 1

`2sqrt61~~15.62" to 2 dec. places"`

Explanation:

`"using "color(blue)"Pythagoras' theorem"`

`"if h is the hypotenuse then"`

`h^2=12^2+10^2`

`rArrh=sqrt(12^2+10^2)`

`color(white)(rArrh)=sqrt(144+100)`

`color(white)(rArrh)=sqrt244=2sqrt61~~15.62`
