Half of the cards are red, and half are black. The possibility of him drawing red the first time was

. The possibility of drawing black the second time was also

. To find the possibility of both, simply multiply

by itself. What is

?
The gradient of the line with that equation is -3/4
The measurement of angle a plus 120 must equal to 180 ( as angles on a straight line must equal to 180)
So measurement of angle a is 60 degrees
Measurement of angle b plus 60 plus 60 must equal to 180
So measurement of angle b is 60
I believe it’s A- x=6+36k
Answer:
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
