Here, we have given, A + B = 225o Operating both sides by cot,  Cot (A + B) = cot225o or, [cotAcotB - 1] / [ cotB + cotA] = 1 [ Since, using formula of cot(A+B) & cot225o = 1.] or, cotAcotB - 1=   cotB + cotA or,  .....

Here, you can write the given question as, 3cosA + 3cosB = 4 sinA + 4 sinB or, 3( cosA + cosB) = 4( sinA + sinB) Now, use formula 

SinC + SinD = 2Sin(C+D)/2.Cos(C-D)/2

&

CosC + CosD = 2Cos(C+D)/2.Cos(C-D)/2 and .....
