Question

a tower stands vertically on the ground. from a point on the ground which is 30 m away from the foot of the tower , there angle of elevation of the top of the tower is found 30 * find the height of the tower​

Answer 1

Answer:

let AB be the height of the tower

• and let C be the point on the ground such that it is 30m from the foot of the tower that is from B. It is given that the angle of elevation is 30 degree by applying formula of tan 30 degree that is 1/square root 3 that is AB/BC=AB/30 =1/square root 3 then cross multiplying the digits we get the height of the tower as 10 square root 3
