Polygon abcd is a parallelogram, and ∠. the length of is 10 units, and the length of is 5 units.

the perimeter of the parallelogram is [blank]
units, and ∠ 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°

(a) based on al the data, miguel had the greatest speed because he did the training once in just 85 seconds.
(b) get the modes of two data sets and compare the spread. the answer is adam
(c) this means that miguel is not consistent although he is able to do the training at a faster rate. adam is more consistent but is not as fast as miguel.
