Answer:

Since AB=AC and LA=90 deg

Therefore LB=LC=45 deg

Therefore sin B . cos C + tan B = sin(45) . cos(45) + tan(45)

                                                   = 1/sqrt(2)   .   1/sqrt(2)    +      1

                                                   = 1/2   +   1

                                                   = 1.5
