Answer:

#color(blue)(csc (30) = 1 / sin 30 = (1 / (1/2)) = 2#

Explanation:

#theta = -330^@# can be written as #-330 + 360 = 30^@#

#30^@# is an angle in the first quadrant where all the trigonometric functions are positive.

enter image source here

#csc (30) = 1 / sin 30 = (1 / (1/2)) = 2# from the table above, #sin 30 = 1/2#

#csc (30) = 1 / sin 30 = (1 / (1/2)) = 2#
