Answer:
4.05 is greater than 0.45
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
I'm just guessing but if you subtract the 1 from 11 and divide by 2 on both sides then T would equal 5
