An airplane departs an airport and climbs to an altitude of 3,300 feet. the airplane descends 400 feet before climbing 1,200
feet more. what is the airplane's attitude now?
3500 feet
3.700 feet
3,900 feet
4,100 feet

i will pick c put check it over to be sure

step-by-step explanation:

the two may have that, even a breakdown is probably offered

find the magnitude of the trig term  

csc

(

x

)

−

1

by taking the absolute value of the coefficient.
