Question

From a tower of 80 m high, the angle of depression of a bus is 30. How far is the bus from the tower?

Answer 1

Answer:

$20\sqrt{23}$ metres

Step-by-step explanation:

in the diagram it is clear that the tower height is 80 m and the angle is 30 degrees

so here we can use sin 30 = 1/2 = P/H

p=80 degrees

let hypotenuse be xthen

1/2=80/x

x=160 m

now by pythagoras theorem we can easily find out the distance
