Answer:
Below.
Step-by-step explanation:
I'll write sin x as s and cos x as c so we have:
(1 + s +c)/(1 + s - c) = (1 + c)/s
Cross multiplying:
s + s^2 + cs = 1 + s - c + c + cs - c^2
s + s^2 + cs = 1 + s + cs - c^2
s^2 + c^2 + s - s + cs - cs = 1
s^2 + c^2 = 1.
- that is sin^2 x + cos^2 x = 1 which is a known identity.
Therefore the original identity is proved.

35 - 14 = 21
3 * 6 = 18
3.5 * 6 = 21
Thus Juan is around the age of 3.5 and Lola is 31.5 I believe
Im not quite sure however I think this is the answer, I hope it helps ^-^
Each person was to have 1.5 pounds of turkey, but, with the extra people she would have to buy an additional 4.5 pounds of turkey. If she didn’t buy anymore turkey then everyone would get 1.25 pounds of turkey, which is about 1/6 less of what they would have originally gotten. 1/6 is equal to 16.7% or 0.167.
