I had asked help for a question and Steve gave me this answer on how to set up equation

Question

20-x/6.11=tan28 degrees
The answer is approx 16.75 ft.

I still don't know how to do this! When I do it I get different answer. Could you please break this down step by step so I can understand? Thank you so much

Answer 1

Just do things as you normally would.
tan 28 = 0.5317, so you have

(20-x)/6.11 = 0.5317
20-x = 3.25
x = 16.75

Don't forget your algebra I just because you're taking trig now!
