sketch the triangle and find the indicated side x or angle theta. <A = 50 degrees, b=23 c= 12 and Line BC= x
use the law of cosines: x^2 = b^2 + c^2 - 2bc*cos(50) solve for x.
okay but how would the sketched triangle look like?
anytime you have a triangle with two sides given and the angle between them given, this is a case for the law of cosines.
