I think, you need to solve for A. For this, Use sinC+sinD formula, i.e;  sin3A+sinA=sin2A or, 2sin(3A+A)/2 cos(3A-A)/2=sin2A or, 2sin2A cosA-sin2A=0 or, sin2A(2cosA-1)=0 either, sin2A=0........................solve it. or, 2cosA-1=0, .....

Here, TanA = b /a = P/B. So, hypotenuse will be H = √(a^2+b^2)  sinA = P/H =  b/√(a^2+b^2)  cosA = B/H =  a/√(a^2+b^2)  Now, LHS = acos2A+bsin2A  =a(cos^2 A - sin^2A) + .....

We know, 70o = 50o + 20 o take tan of both sides  tan 70 = (tan 50 + tan 20)/(1- tan 50 tan 20)  But as,  20 + 70 = 90   ==> 70 = 90 - 20  Operating both sides by tan,     tan 70 = .....
