Answer:
70.1 ft
Step-by-step explanation:
The cosine relation gives the ratio of the adjacent side to the hypotenuse for an acute angle in a right triangle:
Cos = Adjacent/Hypotenuse
cos(37°) = SQ/QR
Rearranging gives ...
QR = SQ/cos(37°) = (56 ft)/0.798636 = 70.1 ft
The length of QR is about 70.1 ft.
Because BE and CD are parallel angle DBE = BDC
BDC is given as 36
The answer is 36 degrees
