Answer:
(For the first two questions I do believe that you will need a protractor to calculate the angles.)
15) [tex]-(\frac{7\pi }{18} )\\[/tex] measures out to -70° in order to display that the angle would be in quadrant IV (the bottom right quadrant.)
The first image attached shows where the angle should be located.
16) [tex]\frac{\pi }{3}[/tex] is equal to 60° (the line you draw will be in quadrant 1 (the top right quadrant))
17) 350° is [tex]\frac{35\pi }{18}[/tex] or 6.11 (the answer depends on the format the professor wants.)
18) 240° is [tex]-(\frac{4\pi }{3})[/tex] radians or -4.19 (I am rounding to the nearest hundredths place the unsimplified answer is −4.18879020...)
