If we join the Center with different corners of the polygon,we find 10 Isoceles triangle with equal side=9.14cm, Making an angle of 36° between the equal sides.
Area of 1 triangle= a*b*sinC/2
= 9.14*9.14*Sin36°/2
= 9.14*9.14*0.587/2
=24.51 cm^2
Area of 10 triangle= 24.51*10
= 245.1cm^2
Answer:

b) 75
Step-by-step explanation:
Alright so your budget is 154 so that already means you cant spend more than
$154. So the uniform is $12 so the inequality could start as:
154 is less than or equal to 12 plus the number of karate classes, which would be;
154 ≤ 12 + 8c
so the answer is B
B. 154 ≤ 12 + 8c
