9 meters
Step-by-step explanation:
We know the hypotenuse is 15 and one leg is 12
a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the legs
12^2 + b^2 = 15^2
144 + b^2 = 225
Subtract 144 from each side
144-144 +b^2 = 225 -144
b^2 = 81
Take the square root of each side
sqrt(b^2) = sqrt(81)
b = 9
