Right side of the equation:
cos ( A - B ) - cos ( A + B ) =
= cos A cos B + sin A sin B - ( cos A cos B - sin A sin B ) =
= cos A cos B + sin A sin B - cos A cos B + sin A sin B =
= 2 sin A sin B - left side of the equation ( correct )
6.50-2.25=x
x is how much Jackson's lunch was
Yes they both are, obviously since their aligned straightly and with he right angle
The answer for your problem is letter B
x=-2 + 2i
I hope its useful :)
