2. A vacant lot shaped like a triangle is between two streets that intersect in an angle that measures 85 degrees The longest side, which is 140 feet long, is opposite that angle. Determine the length of the shortest side
if the angle opposite that side measures 28°

B

C

Step-by-step explanation:

Infinite geometric series converge if the common ratio is between -1 and 1, exclusive.

A has a common ratio of -3, so it does not converge. B has a common ratio of 1/3, so it converges. C has a common ratio of 1/2, so it converges. D has a common ratio of 5/4, so it does not converge.
