Answer 7

Yeah so

Sum of measure of interior angles=540

Now Add all the angles up and equate it equal to 540

Answer 8

well with the three i know the 148 112 and 90 they add up to 350

Answer 9

Also 2x+10 and 2x add them up too.

Answer 10

so then 350=2x+10=2x? to find x?

Answer 11

Noo

Answer 12

how do i find x from there?

Answer 13

I said add all the angles

So,

148+122+90+(2x+10)+2x=540

Now solve for x :)

Answer 14

oh ok

Answer 15

so then x=45?

Answer 22

oh its 112 not 122

Answer 23

148+112+90+2x+10+2x=540
350+2x+10+2x
360+4x?

Answer 24

haha lol :P

Answer 25

360+4x=540

Answer 26

Then your answer is correct,Its 45 :)

Answer 27

then i took
360+4x=540
-360 from both sides
4x=180
then divide?
