Answer: x = 27 degrees
Step-by-step explanation:
ABC and DE are parallel. Angle ABD and BDE are the same because they are corresponding angles. 72 degrees + 2x + 2x = 180 degrees because ADF is a straight line and angles on a straight line add up to 180 degrees. 180- 72 = 108. 4x = 108 degrees, so x = 27 degrees
3 x 4 = 12
618 divided by 12 = 51.5
However, you left a space between the 6 and the 8, so just in case that was meant to be 6.18, here
6.18 divided by 12 = 0.515
Just add it up. So, 200+40+13= 253
