Answer:
x = 30
Step-by-step explanation:
110 and 3x - 20 are supplementary angles, sum to 180° , then
110 + 3x - 20 = 180
90 + 3x = 180 ( subtract 90 from both sides )
3x = 90 ( divide both sides by 3 )
x = 30
The correct answer is: Opposite angles of a parallelogram are congruent.
In a parallelogram, the opposite angles are always congruent. The opposite angles are the angles diagonal across from each other.
You can tell by the order of ABCD that A and C are opposite. B and D are also opposite of each other and congruent.
