convert 16%, 12.8%, 6.4%, 28.8% to angle measures (have to add up to 360degrees)?

Answer 1

16%=57.6
12.8%=46.08
6.4=23.04
28.8=103.68
these add up to 230.4 degrees but it could be since all the precenages given add up to a number less than 100

Answer 2

I'm guessing that you're asking what 16% etc. of a full circle is rather that what a 16% grade is (which is 16% of 90°). So
16% of 360 means .16*360 = 57.6°. Just do all the rest the same way. (12.8% means .128 etc.)

Answer 3

16% of 360
=0.16*360=57.6 degrees
12.8% of 360
=0.128*360
=46.08 degrees
6.4% of 360
=0.064*360
=23.04 degrees
28.8%of 360
=0.288 of 360
=103.68 degrees
