Answer:
x = 13.86
y = 6.93
Step-by-step explanation:
tan 30° = y/12
0.5774 = y/12
y = 12(0.5774) = 6.93
cos 30° = 12/x
0.8660 = 12/x
x = 13.86
1 inch drop for every 25 inches length
40 feet= 12 x 40 = 480 inches
There are 19.2-25 inch lengths in 480 inches.
So there is a 19.2 inch drop in 40 feet.
Hope this helps :)
