Answer 1

Answer:

(For the first two questions I do believe that you will need a protractor to calculate the angles.)

15) $-(\frac{7\pi }{18} )$ 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) $\frac{\pi }{3}$ is equal to 60° (the line you draw will be in quadrant 1 (the top right quadrant))

17) 350° is $\frac{35\pi }{18}$ or 6.11 (the answer depends on the format the professor wants.)

18) 240° is $-(\frac{4\pi }{3})$ radians or -4.19 (I am rounding to the nearest hundredths place the unsimplified answer is −4.18879020...)
