The answer is C The distance between the points (15,6) and (21,22)
The answer to this is not possible because sss would be just one angle and they want it to form a congruent triangle
If u add up 15,17, and 19 they add up to 51
This is a linear function. Let diameter (inches) be x, circumference (inches) be y, observe that the value of y/x is always 3.14. For example, 15.7/5=31.4/10=...=3.14. Therefore, this is not only a function (one to one correspondence from x to y), it's also a linear function that can be represented as y=3.14x.
