Answer:
If the complement of an angle is 25 degrees, then the measurement of the angle will be 65 degrees.
The difference is 180 is the correct answer for the problems
Tank A capacity = 550 gallons 66% x 550 gallons = 363 gallons in Tank A
How about the water in tank B?
ratio of 11: 15 11/15 = 550/x 550 * 15/11 = cap B = 750 gal 53% 0f 750 = .53 x 750 = 397.5 gal in tank B
