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
For the Fist One it’s Pentagonal Pyramid
435 being the constant means that is what they started with
Hope this helps :)
Answer:
25.1cm
Step-by-step explanation:
since circumference =
d and d=2r
c=
(2*4)
c=8
c=25.132741229
c=25.1cm
