(1) A ramp for unloading a moving truck, has an angle of elevation of 30°. If the highest of the ramp is 0.Nine m above the bottom stage, then find the length of the ramp.
(2) A lady of peak One hundred fifty cm stands in entrance of a lamp-post and casts a shadow of duration 150 √Three cm at the ground. Find the angle of elevation of the highest of the lamp-post.
(3) Suppose two insects A and B can hear each different up to a variety of 2 m.. The insect A is on the ground 1 m away from a wall and sees her friend B at the wall, about to be eaten via a spider. If A sounds a warning to B and if the angle of elevation of B from A is 30°, will the spider have a meal or not ? ( Assume that B escapes if she hears A calling ) Solution
(4) To find the cloud ceiling, one night time an observer directed a focus vertically at the clouds. Using a theodolite placed one hundred m from the highlight and 1.5 m above the ground, he found the angle of elevation to be 60°. How top was once the cloud ceiling? (Hint : See figure)
cloud is present. The cloud ceiling at airports should besufficiently top for protected take offs and landings. At nightthe cloud ceiling can also be determined via illuminating the base of the clouds via a focus pointing vertically upward.) Solution
(5) A simple pendulum of length Forty cm subtends 60c at the vertex in one complete oscillation. What would be the shortest distance between the initial place and the final position of the bob? (between the intense ends)
(6) Two crows A and B are sitting at a top of 15 m and 10 m in two different bushes vertically opposite to one another . They view a bread (an eatable) at the flooring at an angle of depression 45° and 60° respectively. They start on the identical time and fly at the identical pace along the shortest path to select up the bread. Which chook will reach it? Hint : (foot of two timber and bread (an eatable) are in a immediately line) Solution
(7) A lamp-post stands at the centre of a round park. Let P and Q be two issues on the boundary such that PQ subtends an angle 90° on the foot of the lamp-post and the angle of elevation of the highest of the lamp submit from P is 30°. If PQ = 30 m, then in finding the peak of the lamp put up. Solution
(8) A person in an helicopter flying at a top of seven-hundred m, observes two gadgets mendacity opposite to each other on either bank of a river. The angles of depression of the objects are 30° and 45°. Find the width of the river. ( √3 = 1.732 ) Solution
(9) A person X standing on a horizontal airplane, observes a chook flying at a distance of 100 m from him at an angle of elevation of 30c. Another individual Y status on the roof of a 20 m high construction, observes the fowl at the similar time at an angle of elevation of 45°. If X and Y are on the opposite facets of the chook, then find the distance of the fowl from Y. Solution
(10) A pupil sitting in a study room sees a picture at the black board at a top of 1.Five m from the horizontal level of sight. The angle of elevation of the image is 30°. As the image is not clear to him, he moves instantly in opposition to the black board and sees the image at an angle of elevation of 45°. Find the distance moved by means of the student.
(11) A boy is standing at a ways from a 30 m tall building and his eye degree from the bottom is 1.Five m. The angle of elevation from his eyes to the top of the construction will increase from 30° to 60° as he walks in opposition to the construction. Find the gap he walked in opposition to the development.
(12) From the highest of a lighthouse of peak 2 hundred feet, the lighthouse keeper observes a Yacht and a Barge along the similar line of sight . The angles of depression for the Yacht and the Barge are 45° and 30° respectively. For protection purposes the 2 sea vessels must be at least 300 ft aside. If they're lower than 300 feet , the keeper has to sound the alarm. Does the keeper have to sound the alarm ? Solution
(13) A boy standing on the flooring, spots a balloon shifting with the wind in a horizontal line at a continuing height . The angle of elevation of the balloon from the boy at an instant is 60°. After 2 minutes, from the similar point of observation,the angle of elevation reduces to 30c. If the rate of wind is 29 √3 m/min. then, in finding the peak of the balloon from the ground stage. Solution
(14) A straight highway results in the foot of a tower . A man status on the top of the tower spots a van at an angle of depression of 30 c. The van is coming near the tower with a uniform pace. After 6 minutes, the angle of depression of the van is located to be 60°. How many extra mins will it take for the van to reach the tower?
(15) The angles of elevation of a synthetic earth satellite is measured from two earth stations, situated at the similar side of the satellite, are discovered to be 30° and 60°. The two earth stations and the satellite tv for pc are in the same vertical aircraft. If the space between the earth stations is 4000 km, to find the gap between the satellite tv for pc and earth. ( √3 = 1.732) Solution
(16) From the top of a tower of peak 60 m, the angles of depression of the top and the bottom of a development are noticed to be 30° and 60° respectively. Find the peak of the construction. Solution
(17) From the highest and foot of a Forty m top tower, the angles of elevation of the top of a lighthouse are found to be 30° and 60° respectively. Find the peak of the lighthouse. Also to find the space of the top of the lighthouse from the foot of the tower. Solution
(18) The angle of elevation of a soaring helicopter as observed from a point 45 m above a lake is 30° and the angle of depression of its mirrored image in the lake, as observed from the same level and on the similar time, is 60°. Find the space of the helicopter from the skin of the lake.
