2x+ x =180 degree( being co interior angle)
3x =180
x=180/3
x=60 degree
Here ,
Angle BCD=2x
=2*60
=120 degree

BCD= 120 degrees. explanation: the 4 angles of a parallelogram must equal 360 degrees. so you add all 4 angles & get 6x. you then take that 6 & divide it from 360 (360/6) and get 60. therefore x=60. so then you just multiple BCD (2x) by 60 and you get 120 degrees

Joan’s washing machine tub is a cylinder with a height of 17 in. and a diameter of 22 in. Her washer was half full of water when

xxMikexx [17]

Find the volume of the cylinder and divide by 2:

V = pi * r^2 * h

V = 3.14 * 11^2 * 17

V = 6458.98

Divide by 2 since it's half full:

6458.98 / 2 = 3229.49

Now divide it by 46.2 to see how long it will take to drain out:

3229.49 / 46.2 = 69.902

So it will take approximately 70 seconds to drain out.
