Answer 1

Answer:

21/4

Step-by-step explanation:

3cos^2 30 + tan^2 60 = 3($(\sqrt{3}/2)^{2} + (\sqrt{3} )^{2}$

                                     = 3(3/4) + 3

                                     = 9/4 + 3

                                     = 9+12 / 4

                                     = 21 /4
