Hi,


I have a 90 degree triangle with the following sides:

Side A: 65"
Side B: 156"
Side C (hypotenuse): 169"

How can I get the angle between Side A and the Hypotenuse?

This should be the arc cosine of a divided by c, or at least that is what the great Google led me to believe.

angle = sin inverse (opposite side / hypotenuse)
             sin inverse (156 / 169)

yes, or arcsin of b divided by the hypotenuse, or arctan of b divided by a

Homework question? I ask because all the lengths are multiples of 13. In fact the tangent of the required angle is 5/12

Thanks.  I was using the sinh function in Windows calculator.  That's NOT what I needed.
