You have a Black square of side length 2s. A circle whose edges touch the edges of the square is cut out of the center of the square. a Black Diamond placed into the circle so that the 4 corners of the equilateral triangle lie on the edge of the circle. what percentage of the shape remains black

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

df =

both have same length

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
