A trapezoid has 4 sides. You have everything you need, just add them together. The perimeter of this trapezoid is 40.3 inches or 3.358 feet.
If vertical angles are congruent you know
84=4x
21=x
You also know that angle M is supplementary to the angle
, measuring 84. Supplementary means it adds to 180 so if you take the difference you get
180-84=M
96=M
Also M is vertical to the last unknown angle so since vertical angles are congruent the last angle is also 96
