let me try..this is great thanks
33/56! @ajprincess right?
wouldn't tan A and tan b be both negative ? A,B are in 2nd quadrant.....
Since A and B are in the second quadrant tanA and tanB will be negative and ya @gohangoku58 u r right:) so it will be -33/56
Reaally sorrry for nt mentioning it at the beginning @kenneyfamily.
Is that clear @kenneyfamily?
