Find the measure of the central angle that you would draw to represent 12.5% in a circle graph.

45°

Step-by-step explanation:

360° is 100% (or 1, the whole)

so the ratio to use is 360:100 = x : 12.5

the proportionality between 360 and 100 must be the same as between the unknown value x and 12.5 (this is more or less the meaning in words), which leads to

x = (12.5*360)/100 = 45°

Another way of seeing it: 12.5% is 1/8 of 100% (therefore 1/8 of 360) so 360/8 = 45°

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
