Question

What is the measure of one of the interior angles of a regular polygon with ten sides?
a. 18 degrees
b. 36 degrees.
c. 144 degrees
d. 162 degrees

Answer 1

use the formula (n-2)/180, where n = number of sides.

Answer 2

sorry, instead of division of 180, it is multiplication of 180

Answer 3

so that is (10-2)*180 = 1440

Answer 4

now, we have to find only one angle, not the sum of all angles

Answer 5

since we know that this is a decagon, it has 10 angles

Answer 6

@moogoo what do you think you should do here?

Answer 7

divide by 10

Answer 8

which number?

Answer 9

the sum of all angles 1440/10

Answer 10

yup

Answer 11

thats exactly right

Answer 12

thanks!!

Answer 13

no problem!
