• Trigonometry -

It does have find all angles of a triangle ABC. little a=6.17,little b=5.25,little c=3.02 . Find CAP A

• Trigonometry -

By the cosine law
6.17^2 = 3.02^2 + 5.25^2 - 2(3.02)(5.25)cosA
cosA = -.043279
angle A = 92.48 degrees

I would then use the Sine Law to find the second angle, and then the "sum of the angles in a triangle" theorem to find the third one.
