Answer: Total cost incurred on new laptop is $318.
Explanation:
Since we have given that
Cost price of new laptop = $300
Sales tax = 6%
total cost of laptop including the sales tax is given by
so,
So, total cost incurred on new laptop is $318.
We have the formula (sin x)^2 + (cos x)^2 = 1;
Then, sin α =
cos β =
We apply the formula sin ( α + β ) = sin α x cos β + sin β x cos α = (3/5)x(4/5) + (4/5)x(3/5) = 12/25 + 12/25 = 24/25;
Then, sin α =
cos β =
We apply the formula sin ( α + β ) = sin α x cos β + sin β x cos α = (3/5)x(4/5) + (4/5)x(3/5) = 12/25 + 12/25 = 24/25;
