Do you know how to work with sin, cos, tan?

#

Yes

Yes

Then for the first photo:

#

You are given the length between the person and the tree (25), the angle at the tree (90°), and the angle at the person (38°).

#

Calculate the height of the tree.

Soh cah Toh?

#

Then add 5ft 3in to the answer, because the height you calculated is from 5ft 3in higher than the tree starts.

#

If you need more explanation I can draw you something, that is gonna take a moment though.

#

I would appreciate that

#

My brain starts hurting when doing stuff with ft and in, so if you want to have the final answer in ft, you have to ro the conversion yourself.

Thanks this actually helps a lot!

#

It’s been a while since I did trigonometric and this gives me a good refresh
