Question 280546
if you draw a line parallel to the base from the top of the left vertical post of 8 feet to the opposite side at the 8 ft mark you form a right triangle with base 10 and vertical leg of 2 (10-8=2)
the roof will be
2^2+10^2=c^2
4+100=c^2
sqrt(104)=c
the top angle can be found using the 10 and the 2 sides of the right triangle and the corresponding trig function.
the other interior angle will be 180-that angle.
