Water Slide The angle of elevation from the base to the top of a water slide is about 28º. The
horizontal length of the slide is about 45 feet.
Find the height h of the slide.
289
45 ft

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
