What is the length of the hypotenuse of a right triangle, whose legs have lengths of 12 meters and 35 meters?

Mercury:

leg^2 + leg^2 = hypotenuse^2 plug in the legs and solve for the hypotenuse

ericcrawford:

47?

Mercury:

pay attention to the exponents ^2 means squared

ericcrawford:

I keep coming up with huge numbers?

Mercury:

hypotenuse^2 = 12^2 + 35^2 solve for hypotenuse. notice that the formula gives hypotenuse^2 so you will have to take the square root of (12^2 + 35^2)

ericcrawford:

144+1225?

ericcrawford:

sorry I'm not good at the mathematical parts at all.

Mercury:

yup then add them together and take the square root of the result

ericcrawford:

37?

Mercury:

good so 37 m is your solution

ericcrawford:

thank you
