Step-by-step explanation:
Step-by-step explanation:
Size of Interior angle = 180° - 360°/n, where n is the number of sides of the regular polygon.
We have 180° - 360°/n = 160°.
=> 360°/n = 20°, n = 18.
Therefore it is a 18-sided regular polygon.
Answer:
2
Step-by-step explanation:
Use the slope formula, given the available points on the line.
m = y2-y1/x2-x1
Plug in the x and y values.
m = 10-2/6-2
Simplify.
m = 8/4 = 2/1 = 2
The slope is 1/2 or m= 1/2
