I am having trouble with a simple Physics problem. It's example 4 the link to the problem is here:
http://img198.imageshack.us/img198/8554/questionf.jpg I can see that tan is side opposite/ side adjacent and I see how that calculates to 4.818, but where does the value of 78.3 degrees come from? It seems to appear from nowhere. I was thinking maybe it was the original angle of 90 degree with respect to ground. 180-90, but that does not equal 78.3 degrees.
Can anyone help me?
Thanks
