I don't understand this question very well

There are 10 marbles in the bag all together.
(8/10) = 80% of the marbles in the bag are white.

So if you pull a marble out of the bag, you have an 80% chance
of pulling a white one.

And if you do it many times, you expect that you'll pull
a white one out about 80% of the times.

   80% pf 45 times  =  0.8 x 45  =  36 times .

Given that sin 2x = cos(2x - 30). Find the value of tan x.​
Paul [167]

Answer:

x=30o+n90on∈Z

Step-by-step explanation:

cos2x=sin(90o−2x)=sin(2x−30o)

Which mean 90o−2x=2x−30o+n360o

or 90o−2x+2x−30o=(2n+1)180o

The later cannot be true.

so x=30o+n90on∈Z
