How to write the co-ordinates
- If a point is x units away from origin horizontally and y units away from origin vertically then the co-ordinates are written in the form of (x-co-ordinates,y-coordinates)
Now write
- D(2,0)
- C(0,7)
- B(-8,-4)
- A(-6,7)
A rational number is any number that can be expressed as the quotient or fraction
Answer:
15
Step-by-step explanation:
Answer:
a) 160°
b) 18 sides
Step-by-step explanation:
Interior angle = 180 - exterior
= 180 - 20 = 160°
Each angle of a regular polygon:
[(n-2)×180]/n = 160
180n - 360 = 160n
20n = 360
n = 18
Alternate approach for no. of sides:
360/n = each exterior angle
360/n = 20
n = 360/20 = 18
