Answer:
3
Step-by-step explanation:
tan2 60 + Cos2 30 / Sin2 30 + Cos2 60
tan 60 = √3
cos 30 = √3/2
sin 30 = 1/2
cos 60 = 1/2
= (√3)2 + (√3/2)2 / (1/2)2 + (1/2)2
= 3 + (√3)2/(2)2 + 1/4 + 1/4
= (3+3 / 4 ) / (1/4 + 1/4)
= (6 / 4) / (1/4 + 1/4)
= 6 / 4) / ( 1+1 /4 )
= ( 3/2 ) / ( 2/4)
= (3/2) / ( 1/2)
= 3/1
= 3
