Suppose a building is erected such that the base of the building is 100 meters from the base of a tower. The angle of elevation from the top of the building to the top of the tower is 80.38 degrees and the angle of depression from the top of the building to the foot of the tower is 65.05 degrees. How tall is the building? How tall is the tower? Round answers to the nearest meter. Be sure to include a picture and all your work for full credit.

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
