Answer:
In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of a triangle to the sines of its angles
The Law of Sines (or Sine Rule) is very useful for solving triangles:
a/sin A=b/sin B=c/sin C
hope this helps
have a good day :)
Step-by-step explanation:
O= 90 because it is a right angle, 360 degrees (which is the whole circle) minus (50+90), equals 220.
There is no graph. If you submit a graph I will answer this for you though.
