Red Circle:
First find the diameter
We can do that by counting the squares
Diameter:4
The radius is half of the diameter
4/2=2
Radius of the Red Circles:2
Blue Circle:
Diameter: 2
2/2=1
Radius of the Blue Circle:1
Answer:
B and C and D
Step-by-step explanation:
This will help,
A linear pair is a pair of angles that form a straight line and are therefore, equal to 180 degrees
3n + 19 + 55 + 33 = 180
3n + 107 = 180
3n = 180 - 107
3n = 73
n = 73/3
so < EFG = 3n + 19 = 3(73/3) + 19 = 73 + 19 = 92
and < GFH = 55 + 33 = 88
