Question

If cotx=5/7,the ^2 is equivalent to what? How do i find quivalent to?
a.)12/7/5
c)5sqrt(74
d)sqrt74

Answer 1

square both sides. if cot(x)=5/7, squaring both sides gives [cot(x)]^2=(5/7)^2.

Answer 2

or do you mean the square root?

Answer 3

the sqrt

Answer 4

makes more sense. do the same operation as I wrote earlier, just \[\sqrt{\cot(x)}=\sqrt{\frac{ 5 }{ 7}}\]

Answer 5

and rationalize.
