Height of back wall is 20.2 ft
Attach is the picture drawn for the question.
First lets find the depth of shed from from front to back wall.
Depth of shed from front to back wall= length of back wall - length of front wall.
∴ Depth of shed from front to back wall=
Now, using sine rule of trignometry to find length of roof line.
We know,
⇒
⇒
Cross multiplying
⇒
∴ Hypontenous= 17.4 feet
Hence, length of roof line is 17.4 ft.
