Answer:
B. A regular polygon having 10 sides if called a regular decagon.
Step-by-step explanation:
Hexagon- 6 sides
Pentagon- 5 sides
Octagon- 8 sides
First one subtract 4/5 and 3 3/4 then divide both sides by the number you get from subtracting.
Add the ratios together:
5 + 2 + 1 = 8
Divide the length of NQ by that:
24/8 = 3
Multiply the ratio of NO by that/l
The ratio of NO is 5, 5 x 3 = 15
NO = 15
