You will just get 18 feet 3inches or 18.3 feet
21g-6f-8g
13g-6f is the answer
combine like terms
I'm not sure about what exactly your teacher is looking for, but the actual congruency conjecture you would use is:
(angle symbol) 1 (congruency symbol) (angle symbol) 8 - Because they are alternate exterior angles
8, 8, 8, 8, 8, 9, 9, 9, 9 would work as a sequence.
Median: 8
Mean: 8.4444....
