I believe the answer is 2.222222222
Let the total number of medals be t. Then (1/3)t=8 and t=24
Also: (1/2)t=12, so that t = 24.
There were a total of 24 medals.

The sum and difference identity cos(x + y) / sin(x - y) = 1 - cotxcoty / cotx - coty is verified
<u>Solution:</u>
Given expression is:
Let us first solve L.H.S
------ EQN 1
We have to use the sum and difference formulas
cos(A + B) = cosAcosB – sinAsinB
sin(A - B) = sinAcosB – cosAsinB
Applying this in eqn 1 we get,
Taking -1 as common from numerator and denominator we get,
= R.H.S
Thus L.H.S = R.H.S
Thus the given expression has been verified using sum and difference identity
