Question

What is the length of the hypotenuse of the triangle when x = 12?
4x + 5
3x

Answer 1

64.1

Explanation:

Let c be the length of the hypotenuse of the right triangle given. If x = 12, then the two legs of the right triangle are 53 and 36 (just substitute x for 12). Using the Pythagorean:

`53^2+36^2=c^2`

Solve for c to get 64.07027391... which is 64.1, rounded to the nearest tenth.

Hope this helps :)
