Question

If 3 sine square theta is equal to 2*1/4 .....theta is less than 90 degree find the value of these

Answer 1

Answer:

\sqrt{3}.

3

.

Step-by-step explanation:

As given in the question,

cos8\theta\ =\ sin\thetacos8θ = sinθ

=>\ sin(90-8\theta)\ =\ sin\theta=> sin(90−8θ) = sinθ

=>\ 90-8\theta\ =\ \theta=> 90−8θ = θ

=>\ 9\theta\ =\ 90=> 9θ = 90

=>\ \theta\ =\ 10=> θ = 10

Now, we have to find the value of

tan6\thetatan6θ

=\ tan(6\times 10)= tan(6×10)

=\ tan(60)= tan(60)

=\ \sqrt{3}=

3

Hence, the value of tan6\thetatan6θ will be \sqrt{3}.
