If the ratio of the height of a tower and the length of its shadow on the ground is √3 : 1, then the angle of elevation of the sun is:
60°
Height to shadow ratio \(\sqrt3:1\) means \(\tan\theta = \sqrt3\).
\(\theta = 60^\circ\).
Hence, the angle of elevation of the sun is 60°.
If x is the distance of P from the bottom of the pillar, then consider the following statements :
1. x can take two values which are in the ratio 1 : 3
2. x can be equal to the height of the flagstaff
Which of the statements given above is/are correct?
What is a possible value of tan θ ?
A vertical tower standing on a levelled field is mounted with a vertical flag staff of length 3 m. From a point on the field, the angles of elevation of the bottom and tip of the flag staff are 30° and 45° respectively. Which one of the following gives the best approximation to the height of the tower?
Two poles are 10 m and 20 m high. The line joining their tops makes an angle of 15° with the horizontal. The distance between the poles is approximately equal to
The angle of elevation of the top of a tower from a point 20 m away from its base is 45 °. What is the height of the tower?
