Answer:
5
Step-by-step explanation:
40 divided by 16 = 2.5
2*2.5=5
Cotx = cosx/sinx
cscx = 1/sinx
If we plug these into your equation we get:
(cosx/sinx)/(1/sinx) - 1
Dividing by a number is the same as multiplying by its reciprocal so it can be rewritten as:
(cosx/sinx)(sinx) - 1
The two sinx's cancel each other out so we end up with cosx - 1
Well if finding X you get 4,-7 when you simplify the whole equation you get that as well.
