Question

A pilot is flying over a straight highway. He determines the angles of depression to two mile posts, 5 miles apart, to be 32 degrees and 48 degrees.
a) Find the distance of the plane from point A
b)Find the elevation of the plane.

Answer 1

Mmm nope. o:
the picture I made was pretty much taken a direct replica from the book.

Answer 2

k. Remember Z angles from geometry? That's how I got the bottom two, the top i just subtracted the 32 and 58 from 180. Now you can use the sine rule to find a.

Answer 3

i got 4.31 miles. o.o

Answer 4

no waittttttt

Answer 5

a/sin48 = 5/sin100

Answer 6

3.77

Answer 7

yeah!!! I already got part b done too so thanks for you help again. xD haha

Answer 8

Welcome :)

Answer 9

Yep, once you have a, finding the altitude of the plane is simple.
