271 rounded is 300, and 425 rounded is 400, so you could estimate the sum by adding 300 and 400, which equals 700.
C)55,556 take 500 x 1,000 and get 500,000 then devide by 9 to get 555.5555556 round to 55,556 plz mark brainliest! :)

I DONT KNOW BUT THAT'S MY ANSWER HOPE IT HELP
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.
