First you must know that for remarkable angles: cos (0) = 1, cos (π) = - 1, cos (π / 2) = 0, cos (3π / 2) = 0, cos (2π) = 1. Then, by simple substitution in the given formula, you can find the solutions of x. Which for the interval [0, 2π) are: x = π, x = pi divided by two and x = three pi divided by two.Attached solution.
is there anther way you can put the pic i cant see
Hello from MrBillDoesMath!
Answer:
68
Discussion:
85% of 80 =
(85/100) * 80 = => as 85* 8 = (80 +5) * 8 = 640 + 40 = 680
6800/100 =
68
Thank you,
