I did d=rt
d=900(5/60)
=75km
not sure where to go from there Answer by mananth(16946) (Show Source):

An airplane traveling at 900 kph
is descending at an angle of depression of 10°. How many kilometers
will the plane descend (vertically) in 5 minutes?
speed = 900 kph
time = 5 minutes = 1/12 hours
d= 900 * 1/12
d =75 km
cos 80 = AB/AC
AB = 75 * cos 80
AB = 75 * 0.173
13 km drop
