Cotx=cosx/sinx
cot²x=cos²x/sin²x
cscx=1/sinx, cscx+1=1/sinx +sinx/sinx=(1+sinx)/sinx

cot²x/(cscx+1)=(cos²x/sin²x)*(sinx/(1+sinx)=cos²x/[sinx(1+sinx)]

Recall that sin²x+cos²x=1, so cos²x=1-sin²x=(1+sinx)(1-sinx)

therefore: cos²x/[sinx(1+sinx)] can be written as
(1+sinx)(1-sinx)//[sinx(1+sinx)]=(1-sinx)/sinx=the left side.

To answer this question here is what you would do. I can't give you the exact answer because there is not a line plot attached.

Count the number of X's above the number 5 1/2 feet. Put this number over the total number of X's you count (including the 5 1/2s).

This is your answer when you write these 2 pieces of information in fraction form.
