6 is 25% of 24. 6 times 4 = 24
Sin404 = sin(360 + 44)
as sin(360 + α) = sinα
= sin44
The answer will be 8.39 because the third number (8) is above 5 so you have to round up. Good luck!
Answer:
Option A.
Step-by-step explanation:
It is given secθ = - 
then cosθ = -
Now we know the identity
sinθ = 
= 
= 
Now sin2θ = 2sinθcosθ
Now we put the values of cosine and sine in the formula
sin2θ = 2×(-
)(
)
= -
Therefore, option A. is the answer.
