  • Question 1
    1 / -0

    Two poles are 10 m10\ m and 20m20\,m high. The line joining their tops makes an angle of 1515^\circ with the horizontal. The distance between the poles is approximately equal to

  • Question 2
    1 / -0

    A person standing on the bank of a river observes that the angle subtended by a tree on the opposite bank is 60o{60}^{o}, when he retires 40m40m from the bank he finds the angle to 30o{30}^{o}. The breadth of river is

  • Question 3
    1 / -0

    The angle of elevation of the top of a TV tower from three points A,BA, B and CC in a straight line through the foot of the tower are α,2α\alpha, 2\alpha and 2α2\alpha respectively. If AB=aAB = a, the height of the tower is

  • Question 4
    1 / -0

    The base of a cliff is circular. From the extremities of a diameter of the base, angles of elevation of the top of the cliff are 30{ 30 }^{ \circ } and 60{ 60 }^{ \circ }. If the height of the cliff be 500 m500 \text{ m}, then the diameter of the base of the cliff is

  • Question 5
    1 / -0

    A kite is flying with the string inclined at 75o{75}^{o} to the horizon. If the length of the string is 25m25 m, then height of the kite is :

  • Question 6
    1 / -0

    From the top of a tower, the angle of depression of a point on the ground is 60o60^o . If the distance of this point from the tower is 13+1 \dfrac {1}{\sqrt{3}+1} m, then the height of the tower is :

  • Question 7
    1 / -0

    The angle of elevation of the top of a tower at a point on the ground is 30o30^o. If on walking 20 m toward the tower, the angle of elevation becomes 60o60^o, then the height of the tower is:

  • Question 8
    1 / -0

    A vertical pole PSPS has two marks at QQ and RR such that the portions PQ,PRPQ, PR and PSPS subtend angles α,β\alpha, \beta and γ\gamma at a point on the ground distance xx from the bottom of pole. If PQ=a,PR=b,PS=cPQ = a, PR = b, PS = c and  α+β+γ=180\alpha + \beta + \gamma = 180^{\circ} then x2x^{2} is equal to

  • Question 9
    1 / -0

    The length of the shadows of a vertical pole of height hh, thrown by the sun's rays at three different moments are hh, 2h2h and 3h3h. The sum of the angles of elevation of the rays at these three moments is equal to

  • Question 10
    1 / -0

    The angle of elevation of the top of a tower from the top of a house is 60 { 60 }^{ \circ } and the angle of depression of its base is 30{ 30 }^{ \circ }. If the horizontal distance between the house and the tower be 12 m12\ m, then the height of the tower is
