From a point 750 ft from the base of the building,the angles of elevation to the bottom and top of the mastmeasure 34 degrees and 50 degrees. How tall is the mast?Explanation / Answer
tan (50°)=x/750 ˜ 893.8152 feet (this is to the tower andbuilding top.) tan(34°)=y/750 ˜ 505.8814 feet (this is to the buildingtop and tower bottom) x-y=tower height ˜ 893.8152-505.8814=387.9338 or 387.934 feetto 3 decimal places. Not sure what the angle you are looking for is. Hope it helps.
