WebVIDEO ANSWER: So for this question we are willing to bide cosine, so we have our triangle. Then we have a b and then c is at the right angle. So you're hypotenuse cause … WebIf C is 150 then A +B must be 30. So sinA is maximum when A takes value very close to 30 and cos B is maximum when B takes value very close to 0. In that case 3sinA + 4cosB can take maximum value 3 (1/2)+4 (1) =5.5 which is less than 6, it's given that 3sinA + 4 cosB=6 ..So c =150 not possible. Suggest Corrections.
