Triangles
posted by Greg .
solve any triangles satisfying
alpha = 20 degrees
b = 10
c = 16
b and c are 2 side values and if I use the pythagorean theorem and I get 18.18? Did I do this right?

You had a similar question yesterday.
I answered it but it appears you didn't look at.
It does not state that it is a rightangled triangle, assuming it is results in contradictory results.
