Yes, stop signs are octagon shaped. So, true.
Answer:
<u>46.77 cm</u>
Step-by-step explanation:
Perimeter of the semicircle = Circumference + 2r
- πr + 2r = r (π + 2)
- 9.1 (3.14 + 2)
- 9.1 (5.14)
- <u>46.77 cm</u>
It looks about right to me.
Answer:
The completed reaction is

Answer:
1. The right triangles pass the AA similarity congruence theorem.
2. s/q
Step-by-step explanation:
They are similar since they pass the AA( Angle-Angle) similarity theorem.
Similar triangles have corresponding proportional sides so side z corresponds with side s and side x corresponds with q so we would represent that as
s/q
