So





And

So

It's already in the simplest form.
Check the picture below, is a negative angle, thus, is going "clockwise"
Answer:
Hey there!
We have tangent 29=h/400
Thus, tangent 29 times 400=h
h=221.7 feet.
The height of the kite is 221.7 feet.
Hope this helps :)
If an employee earns 200 dollars for 14 hours work, that means this person gets approximately 14 dollars and 29 cents per every hour.
