**Reiny**, Wednesday, November 14, 2012 at 10:37amlet alpha = a

beta = b

gamma = g , for easier typing

Since a+b = π/2 or 90°

a , b and g can be assigned values in many ways

e.g.

a = 50°, b=40°, and g=10° , then we need tan 50°

a = 70° , b = 20°, and g=50°, then we need tan 70°

So tan a cannot be uniquely determined , and I think the question is bogus.

Check your typing.
