I don’t really know exactly to what degree you need to put in your solution. But I rounded to the nearest tenth degree. A = 112 degrees B= 28 degrees (180-112-40 bc all sides of a triangle must equal 180) C= 40 a= 27.6 (this is the side opposite of angle A) b= 14 (side opposite b) c= 19.2 (side opposite c)
HOW TO SOLVE: c= law of sines, so c/sin(40) = 14/sin(28), multiply both sides by sin(40) so c can be isolated and solved for. c = 14sin(40)/sin(28). Plug into calculator then get answer. c is approximately 19.2. a = law of sines again, so a/sin(112) = 14/sin(28). Multiply both sides again by sin(112) then solve. a = 14sin(112)/sin(28). Calculator again. a is around 27.6
