A right triangle has a leg b=3 and a hypotenuse c=15
how long is the other leg?

sqrt(216) = 6×sqrt(6) ≈ 14.6969

Step-by-step explanation:

Pythagoras :

c² = a² + b²

with c being the Hypotenuse.

so, we have

15² = a² + 3²

225 = a² + 9

a² = 225 - 9 = 216

a = sqrt(216) = sqrt(4×54) = sqrt(4×9×6) = 2×3×sqrt(6) =

= 6×sqrt(6)

The length of the other leg is 14.697

Step-by-step explanation:

a^2 +b^2= c^2

faster, im not sure why but i know it is faster
