862,840 is rounded to 900,000
It’s J, 3 - X would equal 3 - (-2) which turns into 3+2 which equals 5 but 5 is not greater than 10
Cos 210° = cos ( 180° + 30° ) - cos 30° = - √3/2
X + 13 = -4
x = -4 - 13
x = - 17
I am thinking it is the first one..solution is -17
5/3
if you divide both numbers by 8 you will reduce them to their simplest form
