Question

Please help!!!!! MEDAL AND FAN!!!!!

Answer 1

This is the first picture

Answer 2

This is the second one.

Answer 3

sum of exterior angles of a polygon=360

Answer 4

this 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

Answer 5

So 7-2=5*180=900

Answer 6

Is the right?

Answer 7

right

Answer 8

so add up the measures of the 6 angles given and subtract form 900

Answer 9

900-789=111

Answer 10

yes

Answer 11

So number one is 111degrees

Answer 12

How do I the rest

Answer 13

@Vocaloid

Answer 14

@freckles please help

Answer 15

other 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

Answer 16

where n is the number of sides of your polygon, as @welshfella has written before

Answer 17

So I type in the number of sides that the question says?

Answer 18

yes!
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:
\[\Large \frac{{1080}}{8} = 135\]

Answer 19

but how would I find the exterior

Answer 20

the exterior angle is the supplementary angle of the corresponding interior angle:

Answer 21

Ok..... but how do I know how many degrees the angle is

Answer 22

for 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:
180-135= 45 degrees
