Use the special right triangle to evaluate sin 60°, cos 60° and tan 60°. your answers should be exact (not a decimal).
a. sin 60 = 1/2, cos 60 = √3/2, tan 60 = √3/3
b. sin 60 = √2/2, cos 60 = √2/2, tan 60 = 1
c. sin 60 = 1, cos 60 = 0, tan 60 = undefined
d. sin 60 = √3/2, cos 60 = 1/2, tan 60 = √3

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
