Polygon ABCD is a parallelogram, and [tex]m[/tex]∠[tex]ABC[/tex]. The length of is 10 units, and the length of is 5 units.The perimeter of the parallelogram is [Blank] units, and [tex]m[/tex]∠[tex]BCD[/tex] is [Blank]°

Polygon ABCD is a parallelogram
m<ABC = m<ADC = 127

360 - 2(127) = 360 - 254 = 106

m<BCD = m<BAD = 106/2 = 53 
P = 2(10 + 5) = 2(15) = 30

answer
The perimeter of the parallelogram is 30 units, and m<BCD is 53°
