Answer:

The correct option is 3.

Step-by-step explanation:

The distance between two points (x_1,y_1)\text{ and }(x_2,y_2)is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

From the given figure it is clear that the coordinates of C are (-2,0) and the coordinates of D are (2,4).

Using distance formula we get

CD=\sqrt{(2-(-2))^2+(4-0)^2}

CD=\sqrt{(4)^2+(4)^2}

CD=\sqrt{16+16}

CD=\sqrt{32}

CD=5.65685424949

CD\approx 5.66

The distance between C and D is 5.66 units. Therefore the correct option is c.

Find the value of x and y in the parallelogram below.
Delicious77 [7]
In a parallelogram, the opposite angles are equal and the sum of the angles is 360 degrees.

W = Z and Y = X
3y = 3x
Y = X = y
3y + y + 3x + x = 360
3x + x + 3x + x = 360
8x = 360
x = 360/8 = 45

Therefore, x = 45; y = 45
