Question

sin 45 + cos 60 - tan 30.what is the answer

Answer 1

Answer:

6.30382174077

Step-by-step explanation:

sin 45=0.85090352453

cos 60=-0.95241298041

tan 30=-6.40533119665

sin 45 + cos 60 - tan 30

=0.85090352453+(-0.95241298041)-(-6.40533119665)

=6.30382174077

Answer 2

Answer:

(3+5\sqrt{3})/6

Step-by-step explanation:

sin(1/4pi)+cos(1/3pi)-tan(1/6pi)

=sqrt{2}/2+1/2-sqrt{3}/3

=(3+5\sqrt{3})/6
