Answer:
D. 8*x
Step-by-step explanation:
Hello there! A regular octagon has eight sides with the same extension. The perimeter is the addition of each of them. If each side is x units length, then x + x + x + x + x + x + x + x = 8*x is its perimeter.
You're given two angles and the side not between them are congruent, so the AAS theorem applies. (2nd selection)

Answer:
5
Step-by-step explanation:
Answer:
1. 14.5
2. 16
Step-by-step explanation:
1. a^2 + b^2 =c^2
20^2 + 21^2 = c^2
400 + 441 = c^2
841 = c^2
=
29 = c
29/2 = x
14.5 =x
2. c^2-b^2 = a^2
34^2 - 30^2 = a^2
1156 - 900 = a^2
256 = a^2
=
16 = a
