Yuck, trig. I'm doing college trig at this very moment.
the top half (1+(2sinθ)cosθ)=1+sin(2θ)
because 2sinθcosθ=sin(2θ) is an identity

Using polynomial division your answer becomes:
(csc θ)(sec θ)+2
21^2/0.219 = 2013.69863
2 significant figures are the 20, so the answer is 2000
Hello from MrBillDoesMath!
Answer:
I think your formula (2y/x2) is equivalent to
(2*y)/(x^2) where x^2 means x-squared.
If so, then
(2*y)/(x^2) = (2*3)/(4*4) = 6/16 = 3/8
Thank you,
MrB
The are would be 25
and we could make 3 squares. 75
5inches will be left over.
Probability is 0/12 since there are no blue lollipops in the bag.
