Question

A bird fountain is located 6 m from the base of Joey’s apartment building. From his window, Joey can see it at a 51° angle of depression.

To the nearest tenth of a meter, how far up the building is Joey’s window?

Answer 1

we know that
tan = opposite / adjacent

thus tan51° = x/6

can you calculate x ?

Answer 2

8.5

Answer 3

?

Answer 4

not really

what is tan51 ?

Answer 5

I think it would help you a bit more to be wary of distinguishing between angle of depression vs elevation, and how hoblos got that first picture. This may help a little bit more, while still giving the same answer.

Now you need to solve for h, for
\[\tan49= 6/h\]
