A right triangle has a leg length of 12 and a hypotenuse length of 18. What is the length of the other leg?

The length of the leg is 13.416

Step-by-step explanation:

To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras

h = hypotenuse = 18

a = leg 1 = 12

b = leg 2 =

h² = a² + b²

we replace the known values and solve

18² = (12) ² + (a) ²

324 = 144 + (a) ²

324 - 144 = (a) ²

324 - 144 = (a) ²

√180 = a

13.416 = a

The length of the leg is 13.416
