Question

I have entered this into my calculator about ten times andeach time i get the answer 120 x 9.8 x tan18 = 1337.48. Thesqaure root of that = 36.56, NOT 19. Can you please explain what imay be doing wrong. It isn't even realistic for the total to beless than 1000 bc 120 x 9. thanks I have entered this into my calculator about ten times andeach time i get the answer 120 x 9.8 x tan18 = 1337.48.
