Well do 24 - 13.
You should get 11.
N = 11.
If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)
a²+b²=c²
12²+b²=15²
144+b²=225
b²=81
√b²=√81
b=9
1/10 of 3,000
(1/10)(3000/1)
=(1)(3000)/(10)(1)
=3000/10
=300
C
