Question 937597
set up a right triangle with the airplane at the top of the short leg:
---
third angle C:
C = 180 - 90 - 15
C = 75
---
a:
use law of sines:
c/sinC = h/sinH
c = sinC*h/sinH
c = sin(75)*5280/sin(90)
c = 5100.0883628
the airplane traveled 5100 feet horizontally
---
b:
use law of sines:
b/sinB = h/sinH
b = sinB*h/sinH
b = sin(15)*5280/sin(90)
b = 1366.56455814
the airplane traveled 1367 feet vertically
