∠PMO ≅ ∠MON:, Alternate Int. ∠s Thm.
:, Opposite sides of a parallelogram
∠POM ≅ ∠NMO:, Alternate Int. ∠s Thm.
OM ≅ OM:, Reflexive property
:, Segment subtended by the same angle and on two adjacent parallel lines are congruent
3x + 14 = 20 - 2x
add 2x to each side
5x +14 = 20
subtract 14 from each side
5x = 6
x = 6/5 = 1 1/5
Answer: 1 1/5
3(x+10)+2x=220
5x=190
x=38
