50% of a circle is 180 degrees.
25% of a circle is 90 degrees
12 1/2 % of a circle is 45 degrees
Unknown % of a circle is Unknown, but you just have to multiply the percent times 360 degrees to get any answer.

Sorry, I don't find your question very clear.
If you're talking about a circle divided into wedges, like a pie graph, and the percentages above refer to the percentage of the circle in each wedge, then it goes like this:
- Firstly, d) = 100% - 50% - 25% - 12.5% = 12.5%.
- Now, the total number of degrees is 360. So multiply each percentage by 360:
a): 50% * 360 = 50/100 * 360 = 180 degrees.
b): 25% * 360 = 25/100 * 360 = 90 degrees.
c): 12.5% * 360 = 12.5/100 * 360 = 45 degrees.
d) is the same as c) so is also 45 degrees.

a circlee has 360 degrees,
to find the degrees take 25% of 360, etc.
to find the unknown add up the values of the percents and subtract from 100% to get the unknown percentage and then take that percent of 360.
