Amedium water hose can fill a pool in 30 minutes. a larger water hose can fill the same pool in 20 minutes. if both hoses are turned on at the same time, how long will it take to fill the pool?

Ineed asap. 35 points. in order for two polygons to be similar, two conditions must be met. first, all pairs of corresponding sides must be in proportion. second, all corresponding angles must be congruent. prove that angle congruence is not enough, by itself, to establish that two polygons are similar. do this by describing or drawing two polygons that are not similar but whose corresponding angles are all congruent.
