The interior angle of a regular polygon is 162 degrees. how many sides does the polygon have. Show the working

20 sides

Step-by-step explanation:

Interior angle + exterior angle= 180

So,

let the unknown exterior angle be x

Now,

360 / size  of    the exterior    angle = number of sides of the polygon

hope this helps you

please let me know if you have another questions :-)

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
