From the top of aspier the angle of depression of the top and bottom of a tower of height h are theta and phi respectively. Then height of the spier and its horizontal distance from the tower are respectively.

Answer»

`(hcos theta SIN phi)/(sin theta - phi)` and `(h COS theta cos phi)/(sin(theta - phi))`
`(h cos theta cos phi)/(sin(theta +phi)).(h tan theta cos phi)/(sin (theta + phi))`
`(h sin theta phi)/(sin(theta + phi)), (h cos theta cos phi)/(sin(theta + phi))`
NONE of these
