Question

the angle of elevation of the top of the tower is 30 degree and the angle of deviation of the top of the tower from the foot of the building is 45 degree . if the tower is 30 m high , find the height of the building

Answer 1

Answer:

tan30⁰ = 30/x

1√3 = 30/x

x= 30√3

know distance between tower and building is 30 √3

tan45⁰ = y/30√3

1=y/30√3

y= 30√3
