A boy is flying a kite. The string of the kite makes an angle of 60^{o} with the ground. If the height of the kite is 32 m, find the length (in meters) of the string. 
A) 64
B) 32/√3
C) 32√3
D) 64/√3
Correct Answer : 64/√3 Explanation : Sin q = Perpendicular/Hypotenuse Hence, the length (in meters) of the string L= 64/√3

A pole of height h = 60 ft has a shadow of length l= 60 ft at a particular instant of time. Find the angle of elevation (in degrees) of the sun at this point of time. 
A) 30
B) 45
C) 60
D) 40
Correct Answer : 45 Explanation : let, hight of the pole = BC and length of shadow is = AB 
A person standing on bank of the river observes that the angle subtended by a tree on the opposite bank is 60° and when he retires 40m from the bank, he finds the angle of elevation as 30°. Then the breadth of the river is 
A) 40m
B) 20m
C) 22m
D) 35m
Correct Answer : 20m Explanation :
tan 60 =h/x tan 30 = h/ 40+x using eq(1) 
Two men on one sides of a building of height 25 m notice the angle of elevation of the top of the building to be 45^{o} and 60^{o} respectively. Find the distance (in meters) between the two men. 
A) 32(1+ (1/√3))
B) 15/√3
C) 25(1(1/√3))
D) 25√3
Correct Answer : 25(1(1/√3)) Explanation :
