23. As shown in the diagram below, a ship is headingdirectly toward a lighthouse whose beacon is125 feet above sea level. At the first sighting,point A, the angle of elevation from the ship tothe light was 7°. A short time later, at point D,the angle of elevation was 16°.25. Cathy wants to determine the height of the flagpoleshown in the diagram below. She uses a surveyinstrument to measure the angle of elevation to thetop of the flagpole, and determines it to be 34.9°.She walks 8 meters closer and determines the newmeasure of the angle of elevation to be 52.8°.At each measurement, the survey instrument is1.7 meters above the ground.125 ft16°To the nearest foot, determine and state how farthe ship traveled from point A to point D.52.8°34.9°1,7 m-8 mDetermine and state, to the nearest tenth of ameter, the height of the flagpole.24. As modeled below, a movie is projected ontoa large outdoor screen. The bottom of the60-foot-tall screen is 12 feet off the ground.The projector sits on the ground at a horizontaldistance of 75 feet from the screen.601275Determine and state, to the nearest tenth of adegree, the measure of 0, the projection angle.page prism below. The inside of the pool is 16 feetwide and 35 feet long. The pool has a shallowend and a deep end, with a sloped floor connectingthe two ends. Without water, the shallow end is9 feet long and 4.5 feet deep, and the deep end of28. A rectangular in-ground pool is modeled by theDetermine and state the speed of the airplane, toconstant altitude of 6250 feet.

The campground is 0.25 mile from thelifeguard chair. The straight paths from both thecampground and first aid station to the park rangerstation are perpendicular.26.the pool is 12.5 feet long.35 t164.5 t16.5\0.55 mil12.5 ftLakea) If the sloped floor has an angle of depressionof 16.5 degrees, what is the depth of thepool at the deep end, to the nearest tenth ofa foot?L 0.25 mi CIf the path from the park ranger station to thecampground is 0.55 mile, determine and state,to the nearest hundredth of a mile, the distancebetween the park ranger station and the lifeguardb) Find the volume of the inside of the pool tothe nearest cubic foot.chair.c) A garden hose is used to fill the pool.Water comes out of the hose at a rate of10.5 gallons per minute. How much time, tothe nearest hour, will it take to fill the pool6 inches from the top?
