What seven points of x can I put on the x axis over the interval 2pi less than or equal to x less than or equal to 2pi

Is the exact value of sin(pi/3) + cos(pi/6) equal to 1.73?

I do not understand Randy's question.
Anna
sin (pi/3) = (1/2) sqrt 3
cos (pi/6) = (1/2) sqrt 3
sum = sqrt 3 exactly
However sqrt 3 is an irrational number. It can not be expressed exactly by 1.73 or 1.732050808 or any other integer plus decimal fraction

SO my answer would be sqrt 3?

If you are supposed to give exact answer, the only one is sqrt 3
