Answer: 3/2

Step-by-step explanation: sin² 30 + cos² 45 + cos² 30

                                 sin 30=1/2,cos 45=√3/2,cos 30=1/√2

sin² 30 + cos² 45 + cos² 30=(1/2)²+(√3/2)²+(1/√2)²

                                            = 1/4+3/4+1/2

                                            = 1+3+2/4

                                            = 6/4

                         sin² 30 + cos² 45 + cos² 30 = 3/2
