Find the length of the hypotenuse of a right triangle with legs of lengths 9 and 12. If necessary, round your answer to two decimal places.

Question

anonymous · Answer

use the pythagorean theorem a^2 + b^2 = c^2  so then a = 9 and b = 12 and solve for c

anonymous · Answer

there is one right angled triangle  3,4 and 5 - that slould give u a clue

anonymous · Answer

oh yeah.. okay

anonymous · Answer

the pythagorean theorem says that (leg)^2 x (leg)^2 = (hypotenuse)^2 given that the triangle is a right triangle

anonymous · Answer

dont you do the square root after?

anonymous · Answer

yes to find c since c is squared in the equation

anonymous · Answer

i got 15

anonymous · Answer

you can also find the equation using trig to find the angle the triangle makes and using that to find the hypothenuse

anonymous · Answer

15 is correct
