Question

An observer (O) is located 660 feet from a tree (T). The observer notices a hawk (H) flying at a 35° angle of elevation from his line of sight. How high is the hawk flying over the tree? You must show all work and calculations to receive full credit.

Answer 1

please help

Answer 2

The 660 is referring to the adjacent side

We have an unknown h which is the opposite side

Answer 3

What trig function uses the opposite and adjacent side?

Answer 4

Tan

Answer 5

tan(35) = opp/adj

tan(35) = h/660

how do we isolate h?

Answer 6

wouldnt you cross multiply

Answer 7

you'd multiply both sides by 660

Answer 8

you cross multiply when you have two fractions equal to each other

example: x/2 = 5/10

Answer 9

oh yeaaah

Answer 10

it would be 462.13

Answer 11

or h = 462.13

Answer 12

I'm getting 462.136975 which rounds to 462.14

Answer 13

but you have the right idea

Answer 14

so the answer would be h =462.14?
