Thus a and b are the lengths of the two short sides, and c is the hypotenuse. Use the Pythagorean Theorem to compute any missing length. Assume also that A
denotes the angle opposite a, B the angle opposite b, and, of course, C the right angle.
I recommend that in this problem you enter values of the trig functions as fractions.
Suppose a = 5 and b = 12. Then
c =
sin(A)
cos(A) =
