Please enter two angles and one opposite side

If you know the measures of two angles (A and B) and the length of the side (c) between them, you can use the Law of Sines to find the length of the remaining sides (a and b) as:

a/sin(A) = b/sin(B) = c/sin(C) = 2R

Where R is the circumradius of the triangle

Once you have the length of the two remaining sides, you can use the Law of Cosines to find the measure of the angle (C) that is not given as:

c

^{2}= a

^{2}+ b

^{2}- 2ab * cos(C)

You can also use the given angles and side length to find the area of the triangle using Heron's formula or using trigonometric functions like Sin or Cos.

It's important to note that you need to have the measures of two angles and a side to use this theorem. If you have only one angle and one side, it would not be possible to determine the triangle completely.
