The correct answer would be A. -10.6.
You use Pythagorean theorem...a^2+b^2=c^2
a=12ft
b=47-31.. height of the triangle
c=distance between two roof tops
(12)^2+(16)^2=c^2
144+256=c^2
400=c^2, take square root of both sides
c=20ft
Answer: I think A
Explanation: I’m not quite sure but I believe it’s A
