A submersible traveling at a depth of 250 feet dives at an angle of 15 degrees with respect to a line parallel to the water's surface. It travels a horizontal distance of 1500 feet during the dive. What is the depth of the submersile after the dive?Explain how the angle of the dive affects the final depth.

You measure the angle of elevation from the ground to the top of a building as 32 degrees.When you move 50 meters closer to the building,the angle of elevation is 53 degrees. How high is the building?

An airplane is flying at an altitude of 31,000 feet when it begins its descent for landing.If the runway is 104 miles away,at what angle does the airplane descend?
