1.	If sin135-cos240/sin135+xos240=a+rootb then b=
Answer» SIN(90+45)-COS(180+60)/sin(90+45)+cos(180+60) =COS45-[-COS60]/cos45+(-cos60) =(1/√2)-(-1/2)/(1/√2)+(-1/2) =(1/√2)+(1/2)/(1/√2)-(1/2) =1/√2+1/√2-1/2 =-1/2+√2

Answer»

SIN(90+45)-COS(180+60)/sin(90+45)+cos(180+60)

=COS45-[-COS60]/cos45+(-cos60)

=(1/√2)-(-1/2)/(1/√2)+(-1/2)

=(1/√2)+(1/2)/(1/√2)-(1/2)

=1/√2+1/√2-1/2

=-1/2+√2
