Correct option is B
Given
tan θ =
θ is an acute angle
Formula Used
Solution
Based on tan θ, Opposite side = 3 and Adjacent side = 4
Using Pythagoras theorem:
Hypotenuse =
cosec θ =
Final Answer
So the correct answer is (b)
If tan θ = and θ is an acute angle, find the value of cosecθ.

If tanθ + cotθ = 4, then sec2θ × cosec2 θ is equal to:
If tan A = . find the value of
A boy standing 12 m away from a flagpole observes the top of the pole at an angle of elevation of 60^∘. Find the height of the flagpole.
Note: Consider the height of the boy as 0 m .
(Use √3≈2 )
If cosec A = , then the value of sin2A + 2cos2A is:
Expression is equal to:
Simplify:
If tan θ = and θ is an acute angle, find the value of cosecθ.
Simplify: cosecθ(1 – cosθ)(cosecθ + cotθ)
