Answer:

Step-by-step explanation:

cotx/cscx=cosx

Start on the left side.

cos(x)  csc(x)

Apply the reciprocal identity to  csc  (x)  .

cos(x)  1/sin(x)

Simplify  

cos(x)   1/sin(x)cos(x)/sin(x)

Rewrite  cos(x)/sin(x)  as  cot(x)  .

cot(x)

Because the two sides have been shown to be equivalent, the equation is an identity.

cos(x)   csc(x)=cot(x)  is an identity

cot(x)−tan(x)/sin(x)cos(x)=csc^2(x)−sec^2(x)  is an identity

You are correct :)

Let's choose 43° to be our angle. We know the opposite, and want to know the hypotenuse. Sine is the trig. we use for opposite over hypotenuse. 
sinθ = opposite/hypotenuse
sin(43)=27/x
We want to isolate <em>x</em>, so that looks like:
x = 27/sin(43)
Therefore, the value of x is 27/0.682 or ≈39.589 or F
