Answer:
x: length
y: wide
x = 3y and x*y =192
=> 3y^2 = 192
=> y = 8 => x =3x8 = 24
=> Perimeter = (x+y)*2 = (8+24)*2 = 64

Answer:
C. cot theta
Step-by-step explanation:
(csc theta -cot theta )/(sec theta -1)
csc = 1/ sin
cot = cos / sin
sec = 1 / cos
Let x = theta
(1/ sin x -cos x / sin x )/(1/ cos x -1)
Getting a common denominator in the denominator and combining terms
(1- cos x)/ sinx / ( 1 - cos x) / cos x
(1- cosx) (1- cosx)
----------- ÷ ------------
sinx cos x
Copy dot flip
(1- cosx) cosx

Cancel like terms
cos x / sin x
cos / sin = cot
