Try this option:
(1+ \frac{cosx}{sinx})(1- \frac{cosx}{sinx})- \frac{1}{sin^2x}= \frac{sin^2x-cos^2x}{sin^2x}- \frac{1}{sin^2x}=
= \frac{sin^2x-cos^2x-sin^2x-cos^2x}{sin^2x}=- \frac{2cos^2x}{sin^2x}.
or -2ctg²x

PLEASE HELP ASAP <br> TRIGONOMETRY
otez555 [7]

Answer:

11). x = 25.8°

12). x = 67.3°

Step-by-step explanation:

11). By using sine rule in the given triangle,

   cos(x) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

   cos(x) = \frac{27}{30}

   x = \text{cos}^{-1}(\frac{9}{10} )

   x = 25.84

   x ≈ 25.8°

12). By applying tangent rule in the given triangle,

    tan(x) = \frac{\text{Opposite side}}{\text{Adjacent side}}

    tan(x) = \frac{43}{18}

    x = \text{tan}^{-1}(\frac{43}{18} )

    x = 67.29°

    x ≈ 67.3°

A sample of 50 people was randomly chosen, and 60% of them said that they would rather eat breakfast at home than at a restauran
nalin [4]
The answer to this question would be: <span>The new survey’s margin of error will be between 50% and 100% the size of the original survey’s margin of error. 

A bigger sample will result in a narrower margin of error which is a good thing because your data will become more accurate. But twice size will not improve the margin into the half. It definitely became lower than 100% though
