In rectangular form, we have the coordinates 
Answer:
The number of sides the polygon have 9
Step-by-step explanation:
Given in question as :
For The circle , the central angles measure be 40 °
Let the number of sides of polygon = n
Now . as we know
External angle = 
Or , 40° =
Or,
= 40°
Or,
= 40°
So, n =
= 9
Hence The number of sides the polygon have 9 Answer
Answer: 3/20 of the class
Step-by-step explanation:
Add the amount of students that play soccer to amount of students that play volleyball
1/4 + 3/5 = 17/20
Subtract 17/20 (soccer and volley ball) from 20/20 or 1
20/20 - 17/20 = 3/20
Answer is acute and scalene
This triangle is acute since all angles (51, 79, 70) are all less than 90 degrees. It is a scalene triangle as well since none of the sides (10, 12.1 , 11) are equal to each other.
Here are the other definitions to help you in the future
equilateral- All sides are the same. Right - Has one right angle. Obtuse - Has an angle more than 90 degrees. Isosceles - Only two sides are the same. One is different.
