Let alpha and beta be the radiant measures of two angles. Then sin left parenthesis 2 alpha plus 2 beta right parenthesis is equal to

sin2αcos2β + cos2αsin2β

Step-by-step explanation:

Given that

sin(A+B) = sinA cos B + cos A sinB

According to the question;

sin(2α+2β) = sin2αcos2β + cos2αsin2β

where A =  2α and B = 2β

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
