A Geometry ?

Given that two sides of a triangle are 20 and 66. Find the range of possible measures for the third side, s.
a. 20<s<66
b. 46<s<86
c. 20<s<86
d.46<s<66

If you could tell me how to do this problem, i could do my next four.


In the extreme cases, the length of the third side can be either the sum or the difference of the two other side lengths. That is when the triangle reduces to a straight line.

Let that fact guide you in your answer.
