If `A+B=pi/2andsinA+sinB=1` then `sin 2A` is equal to

If Aa n dB are acute positive angles satisfying the equations 3sin^2A+2sin^2B=1 and 3sin2A-2sin2B=0, then A+2B is equal to (a) pi (b) pi/2 (c) pi/4 (d) pi/6

If tan A=(1-cosB)/(sinB) , then tan 2A is equal to

If AandB are acute positive angles satisfying the equations 3sin^(2)A+2sin^(2)B=1 and 3sin2A-2sin2B=0, then A+2B is equal to (a) pi (b) (pi)/(2) (c) (pi)/(4) (d) (pi)/(6)

In DeltaABC,a=2,b=3andsinA=(2)/(3) , then B is equal to

If sin(A+B)=1 sinB=1/2 then A=

If sinA+sinB=(pi)/(4),then (tanA+1)(tanB+1) is equal to

If sinB=1/5sin(2A+B), then (tan(A+B))/(tanA) is equal to

If sinB=1/5sin(2A+B), then (tan(A+B))/(tanA) is equal to
