Question

Calculate the hypotenuse (c). a=12 b=9

Answer 1

The hypotenuse is 15.

Explanation:

The formula to calculate the hypotenuse is a^2+b^2+c^2. Since a=12 and b=9, we can plug those numbers in: 12^2+9^2=c^2.

12^2=144

9^2+81

144+81=225.

Next, we use the square root of 225, which is 15. 12^2+9^2=15^2.

So the hypotenuse is 15.

Answer 2

15


c=a2+b2=122+92=15
