Question

From a tower on a straight road,the angles of depression of two cars at an instant 30° and 45°.If the cars are 30m apart,find the height of the tower.

Answer 1

First draw a triangle with its base as B and C meshuring 30m and make one-one point on the end of the line depcting the 2 cars then draw a perpendicular to lie BC depcting the tower and mark it as AD.

Then from the point A make 2 lines joining the 2 point B and C.

And then find the meashurement of the hight AD.

That will be your ans

Answer 2

So, let's

A triangle with its base as B and C meshuring 30m and make one-one point on the end of the line depcting the 2 cars then draw a perpendicular to lie BC depcting the tower and mark it as AD.

Then from the point A make 2 lines joining the 2 point B and C.

the measure of height is your answer
