Consecutive angles of a parallelogram are supplementary, so:
This means 
and that 
.
Since opposite angles of a parallelogram are congruent,
Answer:
Problem #1) GCF = 5

Problem #4) LCM = 45
Problem #5) 12 and 18
Problem #6) 20 and 40
Step-by-step explanation:
Let me know if you want me to explain these by commenting, and i can write an explanation for each problem! Hope this helped!
Answer:
Step-by-step explanation:
The range is 10
The ratio of one triangle to the other (because they are similar, since the top angles are both 44 degrees and the two sides on the other sides of them are the same) is 12:8, or 3:2.
So therefore, we can say it's 9:6, so DE is 6.
