Exterior angle

8 months agoExterior angles = 360 360/7~51.42 =51.4

8 months agothis|dw:1537391130728:dw| suppose this is a regular 7 sides polygon

8 months agohow you get the measure of an exterior engle ?

8 months agoall exterior angles = 360*?

8 months agomoment one interior angle how many degree will have ?

8 months ago900/7 ~129

8 months agoand so you know that one interior angle toghether with exterior angle need making 360 degrees yes ?

8 months agoyes

8 months agoSo Interior + exterior = 360 Degrees

8 months agojust one

8 months agoexactly

8 months agoyes than you know the measure of one interior angle you can calcule easy the measure of one exterior angle

8 months agook. ?

8 months agoi think so

8 months agothis is the best easy way

8 months agoso 129 + x = 360 360 - 129 = x x = 231?

8 months agoyes right

8 months agothan this 129 is the measure of one interior angle

8 months agoOkay, i need one measure of an exterior angle, and all exterior angles = 360

8 months ago51.4 x 7 = 359.8

8 months agothis 51,4 degrees is the central angle of a regular 7 sides polygon yes ?

8 months agoNo, Im saying one exterior angle of a 7 side Polygon equals 51,4

8 months agoAlso, What language do you speak if it makes it easier i can use a translator

8 months agothis is impossibile bc. than you see my posted drawn there tan exterior angle is greater than 100 degrees - no ? pardon for my english but this not is my mather language - sorry

8 months agoI know it's fine i can understand you. And yes if you add a line to the outside it makes it obtuse

8 months agook. so than you see this my drawn how you think that you can calcule the measure of an exterior angle ? using these traingles

8 months agothese triangles

8 months agouse what you know that one triangle has total angle measure of 180 degrees and you know that the central angle maesure is 51,4 degrees and again you know that the second and 3rd angles are congruent

8 months agoits terrible but just go with it

8 months agoPot să folosesc un traducător pentru a vorbi în limba dvs., dacă doriți să faceți acest lucru mai ușor

8 months ago180-51,4 = x so x/2 is the measure of second and 3rd angle and you know that ohhh mamá hai sá vorbim románeste atunci

8 months ago180 - 51,4 = 128,6/2 = 64,3

8 months agoyes but now you need using what you know that the measure of an exterior angle together with this 128,6 make 360 degrees yes ?

8 months ago128,6 + 129 = 257,6

8 months agocheck please my posted drawn above

8 months agoOkay hold on let me start over, the sum of all exterior angles is 360

8 months agothere are 7 exterior angles

8 months ago360 / 7 = 54.1

8 months agono this is the measure of an interior angle

8 months agoOh

8 months agoOkay

8 months agoSo central angle = 54.1

8 months ago@ThisGirlPretty please do you can help me making more understandably

8 months agointerior = 129

8 months ago128,6

8 months ago128.6 + x = exterior angle?

8 months ago|dw:1537392880359:dw|

8 months ago360 - 128,6 = exterior angle measure

8 months agook. ?

8 months agookay

8 months agoprecis ?

8 months ago231.4

8 months ago231,4

8 months agoyes so thia is the exterior angle maesure of a 7 side regular polygon

8 months agopixel do you understand it now sure ?

8 months agoso 231,4 is the final answer

8 months agoyes bc. than you assume this 231,4 with this 128,6 you get 360 degrees

8 months agoYes Thank

8 months agotry see it in this way - this point A let being the central point of a circle you know that this drawn part has 128,6 degrees so what reamained till 360 degrees bc. you know that a circle has 360 degrees so in this way will get easy the measure of an extreior angle with 360-128,46 yes ?

8 months ago@ThisGirlPretty please do you understand this way ?

8 months agopixel questions ?

8 months agoone more sorry i had to do something
