Anna is watching fireworks launch on the beach. She is sitting on the sand 250 ft from the firework launch point. Anna tilts her head at an angle of elevation of 37° to see the first set of fireworks explode. Five seconds later, the next set of fireworks exploded at an angle of elevation of 64°. To the nearest tenth of a foot, what is the vertical distance between where the two fireworks exploded? Ans: The firefighter academy is running drills with cadets. The fire captain is watching cadets climb a tall vertical ladder. The first cadet he sees is at the 164 feet mark on the ladder. The fire captain is standing on the ground 35 feet from the base of the ladder. What is the angle of elevation that the fire captain must tilt his head to see the cadet? Round to the nearest degree.
