That's true. Opposite sides of a parallelogram are parallel, which implies that the opposite angles are congruent.
Answer:
268 cm
Step-by-step explanation:
A P E X
P=2(l+w)
Substitute width plus 3 for length
Remember order of operations: multiply before adding
86=2((w+3) + w)
86=2w+6+2w
86=4w+6
80=4w
20=w
23=w+3=l
Check the answer
86=2((w+3) + w)
86=2((20+3)+20
86=2(23+20)
86=46+40
86=86
Eleven and five tenths plus another number
