To find:
The angle A and angle B and side c.
Solution:
Given a = 18.5 and b = 14.
if we take tangent of angle A, then

It is known that the sum of all three angles is 180 degrees. So,

Now, we use Pythagoras theorem to find the value of c:

Thus, angle A = 52.49 degrees, angle B = 37.51 degrees and c = 23.32.
