To find the distance between two small towns, an electronic distance measuring (edm) instrument is places on a hill from which both towns are visible. the distance from the edm to the towns is 4.2 miles and 4 miles and the angle between the two lines of sight is 69 degrees. find the distance between the towns to the nearest tenth of a mile.

Solar cell a produces 100 joules of energy, when a light source is shown on it for 3 minutes. solar cell b produces 200 joules of energy when the same light source is shown on it for 5 minutes. which solar cell works better? a) solar cell b, because it produces more energy. b) solar cell b, because it generates more power. c) solar cell a, because it produces energy quicker. d) solar cell a, because it generates a greater wattage. eliminate
