Question

Help Please

Answer 1

For part a), use the formula

A = 180(n-2)/n

where

A = interior angle
n = number of sides

Answer 2

for part b), you subtract the result you got in part a) from 180

Answer 3

Damn I tried it, But getting the wrong answer

Answer 4

show me what you got

Answer 5

I got 144

Answer 6

A = 180(n-2)/n

A = 180(36-2)/36

A = 180(34)/36

A = 6120/36

A = 170

Answer 7

So the interior angle is actually 170

Answer 8

The exterior angle would then be 180 - 170 = 10 degrees

Answer 9

And how if I do part B, Do I subtract 180 from 170?

Answer 10

yep

Answer 11

I have a next question Jim?

Answer 12

Can I post it on the same page?

Answer 13

sure

Answer 14

I got 19, but thats the wrong answer.

Answer 15

solve for 'a'

a/9 = 25/15

Answer 16

Wait so I am simplify more, or is that going to be my answer?

Answer 17

no, you need to isolate 'a'

Answer 18

to get a = ???

Answer 19

Isolate meaning divide?

Answer 20

isolate means get 'a' all by itself on one side

Answer 21

I am so lost

Answer 22

a/9 = 25/15

a/9 = 5/3

a = 9*(5/3)

a = 45/3

a = 15

You're just solving for 'a'

Answer 23

If this is completely foreign to you, I recommend getting more practice with it

Answer 24

or reviewing it in the lesson
