Andrew wants to build a slide for his daughter's tree house. If the tree house is 5 feet off the ground and he wants the slide to have a 60º angle, how long a sliding board does he need to buy? (Round up to the nearest foot.)

Answer 1

For the answer to the question above, I'll provide the solution to my answer below.
sin 60=h/x 
(3^1/2)/2=0,866 
5/0,866=x 

so the answer to the problem is X=6
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
