A verticle flagpole, AB, has a height of 42m. The points B, C and D lie on level ground, and BCD is a straight line. Point C is 24m from the base of the flagpole. The angle of evelation of the top of the flagpole from point D is 48 degrees. How far apart are points C and D?

Write the sentence as an equation. b increased by 281 is d

Can someone pls ! pls answer all. no explanation needed..

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
