An interior angle of a regular convex polygon is 140°. how many sides does the polygon have?

a. 8

b. 9

c. 10

d. 11

B

Step-by-step explanation:

We can use the formula for interior angles of a polygon to solve this. The formula is:

Each interior angle of a polygon =

Where n is the number of sides

We know each angle is 140°, so we plug that in and find n:

The polygon has 9 sides, correct answer B.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
