an airplane traveling at 285 mph is descending at an angle of 5 degrees. How many miles will the plane decrease in altitude in 8 minutes?
**
285%28mi%2Fhr%29%2A%28hr%2F60min%29%2A8min=38+mi(distance plane traveled in 8 minutes)
let x=decrease in altitude in 8 minutes?
tan 5deg=x/38
x=38*tan 5deg≈3.32
Miles the plane will decrease in altitude in 8 minutes≈3.32
