Question 594914
the sizes of angles and their relationships to the lengths of the opposite sides, unfortunately involves trig
___ the Law of Sines states that the lengths of the sides is in the same proportion as the sines of the opposite angles


since A is 105º, B plus C is 75º - like 30º plus 45º


sin(30º) = 1/2 ___ sin(45º) = √2 / 2


looks like angle C is 30º
