Step-by-step explanation:
<u>The Law of Cosines</u>
When we know the value of all sides of a triangle, we can compute all of its interior angles by using the Law of Cosines, which is a generalization of the Pythagoras's theorem. If a,b, and c are the known sides of a triangle and is the angle formed by sides a and b (opposite to c), then
We'll use the values a=190, b=330, c=280 because we want to compute the angle opposite to c
