It is a paralellogram
and the sum of angles of any quadrelateral = 360
14 x+ 14 x + 6x +6x = 360
40 x = 360
x= 360/40= 9
14x = 14* 9 = 126
6x = 6 * 9 = 54

Answer:
- first distribute the 5 to the d and 4
- 5(d+4) then becomes 5d+20
- then subtract 20 from both sides of the equation
- -5=5d+20 is now -25=5d
- lastly divide 5 from both sides
- -25=5d is now -5=d
- hope this helps!
