ratio of perimeter is the same as ratio of sides so perimeter would be 1:4
since area is in square units you need to square the ratio (1:4)^2 which is 1:16
Answer:
12(7 - 3)
Step-by-step explanation:
All the other do not equal anything.
Answer:
108 °
Step-by-step explanation:
∠DOC = 180° - 112° = 68°
∠DOC = 1/2(arc AB + arc DC)
68 = 1/2(y + 80 + y)
68 = y + 40
y = 28
arc dc = 80 + 28 = 108 °
Ab and bc are equal.
Automatically bc = 8v
8v + 8v = 16v
16v = 2v + 42
14v = 42
V = 3
8(3) + 8(3) = 2(3)+42
48=48
Bc = 8v
