5. Jira told Helen that the perfume she used was less dense than water. Helen got a graduated cylinder from the cabinet and found the mass of the cylinder to be 58.35 g. Jira poured 25.0 mL of perfume into the cylinder and massed it again. The combined mass of the cylinder and perfume was 68.80 g. -a. What was the mass of the perfume
-b. What was the density of the perfume?

I think the mass is 35.0 and I can't answer b because I don't know what density is yet

sorry

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
