Will give medal to best answer! the given measurements may or may not determine a triangle. if not, then state that no triangle is formed. if a triangle is formed, then use the law of sines to solve the triangle, if it is possible, or state that the law of sines cannot be used. c = 38°, a = 19, c = 10,

We have two sides and one angle opposite to one of the known sides.

Begin with applying the Law of Sines to find angle A:
= 

Then, solve for sin A:
sin A =

Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17

We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.
