So the length of the arc is given by: l = r*theta, here theta is the intercepted angle in unit radian
So, 80 degrees = 80/360 * 2pi = 4/9 * pi
So l = r * (4/9 * pi), the constant ratio is 4/9 * pi
Two angles are supplementary if their measures sum 180°.
Linear angle pairs are adjacent angles (they are together) and they form a straight angle, which is 180°. Therefore, they are supplementary.
But two angles may be separated and yet add 180°, then they are supplementary but are not linear angle pairs.
The combined amount of cats sold is 117.
Ratio expresses the relationship between two variables. It shows the frequency of which that one value is contained within another variable.
The ratio of Siamese cats to house cats = 4 : 9
Number of Siamese cats = 36
Number of combined cats = c
This equation can be formed using the above information:
4/13 x c = 36
4c = 468
c = 468 / 4
c = 117
