[00:00:02]Hello friends, welcome to before exam.

[00:00:06]part 24 total chapter question chapter question chapter chapter question chapter chapter question question chapter chapter question question question question question question question question chapter question question chapter chapter chapter chapter question question question question question question question question chapter question chapter question 24 question chapter question upcoming exam chapter upcoming chapter Each interior angle of a regular polygon is 100 degree better than uh better than are there in the polygon?

[00:01:37]polygon interior interior interior angle chapter exterior angle exterior exterior angle exterior angle. So, just the time to get the angle separated exterior angle over.

[00:02:02]So, what do you think? Now, that the exterior angle X degree over into the angle get over 100 plus X over 100 plus X degree over. So, 80 to the angle going over 80 to the angle over supplementary to the angle angle the sum get over 180 degree. So, X plus X plus 100 is equal to 180 degree. So, 2X is equal to 180 minus 100 get over 40 80 degree. So, X the value get over 40 degree. So, X the value get over 40 degree. So, exterior angle get over 40 interior angle over 140 degree. So, what does it say? How many side are there in the polygon? The polygon the total side which is get the exterior angle over sum of the exterior angle the polygon the total side over sum of the exterior angle get over 360 degree. So, 5 to the side over 2 to the side over 15 side over 20 to the side over the sum total exterior angle get over 360 degree. Sum of exterior angle get over 360 degree. What the angle get over 40 degree?

[00:02:55]Total get the angle to over not angle to over a little extra angle get over not angle over the side get the total over not a side not a side over not a exterior angle over option D.

[00:03:11]Next the ratio of the number of side of a two regular polygon 1 is to 2. It have a polygon 1 and a polygon 2. The year side get the 1 is to 2 ratio over 200.

[00:03:21]If each each interior angle of the first polygon is 108. So, that would be polygon over here.

[00:03:30]Each interior angle of the polygon over here is 108 degree. The interior angle over here is 108 degree. The exterior angle get the total over exterior angle get the total over 72 degree total.

[00:03:40]We got to listen to the total 180 degree over here. The interior total 108 degree total the exterior total get the total 72 degree total. We got to listen to the total over 180 degree total. The interior total exterior total 72 degree.

[00:03:53]Exterior total 72 total exterior sum 360 360 five the polygon five polygon five the second polygon the measure of interior angle the second polygon the second polygon exterior angle side exterior angle 360 exterior angle 36 degree the interior angle degree the interior interior angle the second polygon degree next if a regular polygon interior angle equal to 175 So interior angle interior angle 175 exterior angle 5 degree exterior angle then we find number of side the polygon the exterior 5 degree sum of the angle 360 degree the 360 degree angle over exterior angle 72 the exterior degree 72 72 option one next the each interior angle regular polygon four times exterior angle polygon polygon exterior angle four times exterior angle exterior angle X degree 4X degree four times 5X 5X 180 degree So X 180 by five 36 degree exterior angle 36 degrees.

[00:05:52]36 degrees. The sum of exterior angle 360 degrees. The good 36 degrees.

[00:05:59]The exterior angle 10 the 10 exterior angle side of 10 the side.

[00:06:05]Number of side of the regular polygon the area side of the side.

[00:06:11]The exact the question complete already put in there.

[00:06:16]The general formula chapter complete the question. So the next session all the topic thank you.
