total students: 545
Now, a whole circle is 360°, so
190/545 * 360 = 125.5°
and similarly for the other angles.
A survey about the student government program at a school finds the following results.
190 students like the program
135 students think the program is unnecessary
220 students plan on running for student government next year.
If a circle graph were made from this data, what would the measure of the central angle be for the group that likes the program? Round your answer to the nearest whole number.
I am not sure could someone help?

this has not been checked yet but if i am correct:
190 students = 125.5 degrees
135 students = 89.28 deg.
220 students = 145.22 deg.
190 students = 125.5 degrees
135 students = 89.28 deg.
220 students = 145.22 deg.
190/(190+135+220) = .3486 .3486*360 total degrees= 125.504
if you round that you get 126 degrees
if you round that you get 126 degrees
