Best ResponseYou've already chosen the best response.1this is a heptagon  with 7 sides formula for number of measure of angles in an n sided polygon = 180(n 2) So plug on n = 7 and you can calculate the total measure of degrees then you can find value of x

Best ResponseYou've already chosen the best response.1so add up the measures of the 6 angles given and subtract form 900

Best ResponseYou've already chosen the best response.1other questions are similar, you have to use this formula: \[\Large s = \left( {n  2} \right) \times 180\] in order to compute the sum of the interior angles of a polygon

Best ResponseYou've already chosen the best response.1where n is the number of sides of your polygon, as @welshfella has written before

Best ResponseYou've already chosen the best response.0So I type in the number of sides that the question says?

Michele_Laino

Best ResponseYou've already chosen the best response.1yes! for example, let's study exercise #5 the sum of interior angles is: \[\Large s = \left( {8  2} \right) \times 180 = 1080\] then each interior angle measures this: \[\Large \frac{{1080}}{8} = 135\]

Best ResponseYou've already chosen the best response.0but how would I find the exterior

Michele_Laino

Best ResponseYou've already chosen the best response.1the exterior angle is the supplementary angle of the corresponding interior angle: dw:1440016538135:dw

Best ResponseYou've already chosen the best response.0Ok..... but how do I know how many degrees the angle is

Michele_Laino

Best ResponseYou've already chosen the best response.1for example, let's study exercise #6 since from exercise #5 we know that the measure of each interior angle is 135 degrees, then the measure of the corresponding exterior angle is: 180135= 45 degrees

Best ResponseYou've already chosen the best response.0How do I do number 2?

Michele_Laino

Best ResponseYou've already chosen the best response.1you have to compute the supplementary angle of each interior angle, then you have to sum those new angles. For example: the corresponding exterior angle of the interior angle of 108 is: 180 108 =72 the corresponding exterior angle of the angle of 133 is: 180133= 47 and so on, please complete

Best ResponseYou've already chosen the best response.0So I get all of the exterior angles and add them?

Best ResponseYou've already chosen the best response.1yes! oops... what is 40+25+45+62+69+47+72=...? in other words you have to compute the corresponding sum

Best ResponseYou've already chosen the best response.1I got this: 40+25+45+62+69+47+72=360

Best ResponseYou've already chosen the best response.0Oh ok lol. I was adding 78 not 72

anonymous

Best ResponseYou've already chosen the best response.0So the answer is 360?

Best ResponseYou've already chosen the best response.0I know that I have a ton of questions and I'm sorry lol. But how do I do 11 to 14?

Best ResponseYou've already chosen the best response.1since each interior angle is 120 degrees, then the sum of all interior angles is: 120*n being n the numbers of interior angles, am I right?

Best ResponseYou've already chosen the best response.1I'm referring to exercise #11

Michele_Laino

Best ResponseYou've already chosen the best response.1so the sum of all interior angles is: 120*n

Michele_Laino

Best ResponseYou've already chosen the best response.1n is a natural number which has to be determined

Best ResponseYou've already chosen the best response.1now, since our polygon has n interior angles, then it also has n sides

Michele_Laino

Best ResponseYou've already chosen the best response.1for example a hexagon has 6 interior angles and 6 sides

Michele_Laino

Best ResponseYou've already chosen the best response.1now I use the general formula for the sum of interior angles: \[\Large s = \left( {n  2} \right) \times 180\] and I can write this: \[\Large \left( {n  2} \right) \times 180 = 120 \times n\]

Michele_Laino

Best ResponseYou've already chosen the best response.1since, as we noted before, s=120*n

Michele_Laino

Best ResponseYou've already chosen the best response.1now I simplify the left side, so i get: \[\Large 180 \times n  360 = 120 \times n\]
