  • Question 1/10
    1 / -0

    Solutions

     

  • Question 2/10
    1 / -0

    The angle of depression of a point from the top of a 200 m high tower is 45 °. The distance of the point from the tower is

    Solutions

    Thus, the distance of the point from the tower = 200 m 
    Hence, option B is correct.

     

  • Question 3/10
    1 / -0

    Evaluate: 3 cos 80 ° cosec 10 °+ 2 cos 59 ° cosec 31 °

    Solutions

    3 cos 80 º.cosec 10 º + 2 cos 59 º.cosec 31 º 

    = 3 cos(90 º – 10 º).cosec 10 º + 2 cos(90 º – 31 º).cosec 31 º 

    = 3 sin 10 º.cosec 10 º + 2 sin 31 º.cosec 31 º 

    = 3 + 2 = 5 

     

  • Question 4/10
    1 / -0

    2 cosec2 23 ° cot2 67 ° − sin2 23 ° − sin2 67 ° − cot267 ° is equal to

    Solutions

     

  • Question 5/10
    1 / -0

    If cos67o.cosecθ = 1 then value of θ is

    Solutions

    Cos67ocosecθ=1

    cos(90-23)cosecθ = 1

    sin23cosecθ =1

    θ = 23o
