Question 1190344
<br>
The sequence of questions is strange, so I will ignore them....<br>
Assuming the sections of roof are all congruent, each one is an isosceles trapezoid.  That means
(1) the non-parallel sides of all the trapezoids are the same length, which is 6 feet;
(2) the base angles are all the same -- 65 degrees;
(3) the other angles are all 180-65=115 degrees.<br>
