Answer 1

!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 2

To solve this expression, we need to find the value of cos(alpha) given that alpha satisfies the equation:

cos(alpha) = 0.3 * sin^2(alpha/2).

However, we can't directly find the value of alpha with the given information. We need another equation or more context to determine the exact value of alpha.

If you have additional information or another equation involving alpha, please provide it, and I'll be happy to help you solve for alpha and then calculate cos(alpha).
