Ahelicopter takes off from the ground 800 feet from the base of a building. it flies in a straight line directly to the top of the building. if the building is 160 feet tall, what angle did the helicopter take off from? round the answer to the nearest whole degree

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
