Answer:
a = 112º
b = 68º
c = 112º
Step-by-step explanation:
this is a paralel stuff so b is paralel to 68 and therefore is also 68. The sum of alngles of poligons with 4 side is usually 360 (this is usually a deformed square) so:
68 + 68 = 136
360 - 136 = 224
since a = c, then a and c are basically 224 / 2 which is 112
