Help medal and fan if i havent already

Find the measure of angle A. Show equations and all work that leads to your answer.

OpenStudy (anonymous):

i need to know whats the total of this hexogon so i can sovle for x

OpenStudy (anonymous):

well to do that wont you need to solve the other numbers as well?

\(\small\sf\color{#ff0000}{Anyone~know~how~to~LaTeX?}\)

OpenStudy (anonymous):

no you do @jojobuck if i can find the max number ill just have to slove x its much easier

OpenStudy (lyrae):

sum of angles = (n-2)*180 n = number of sides

OpenStudy (lyrae):

|dw:1421340498228:dw|

OpenStudy (anonymous):

so it would be (8-2)*180

OpenStudy (anonymous):

??

OpenStudy (lyrae):

I counted 7 sides...

OpenStudy (anonymous):

oppss your right so (7-2)*180

OpenStudy (lyrae):

Yup, look good!

OpenStudy (anonymous):

so it would be 900

OpenStudy (anonymous):

then all i have to do it add equations and make them equal 900?

OpenStudy (lyrae):

Yes exactly!

OpenStudy (lyrae):

Or well, add all equations and angles.

OpenStudy (anonymous):

how i add with angles

OpenStudy (lyrae):

Like you do with the equations Starting from B: 900 = (10x + 2) + 165 + 100 + (5x + 83) + ...

OpenStudy (anonymous):

so i would get rid of the angles by subtracting first right?

OpenStudy (lyrae):

Yes

OpenStudy (anonymous):

ok let me try and get back to you to see if i did it right

OpenStudy (anonymous):

506+27 x sorry was trying to do last step but couldnt figure it out

OpenStudy (anonymous):

was i suppose to leave out A

OpenStudy (lyrae):

No, it should be included (I just left it out of my example).

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

504 = 36x

OpenStudy (anonymous):

14

OpenStudy (lyrae):

almost! Remember you're supposed to set the sum of the equations and angles equal to (7-2)*180.

OpenStudy (anonymous):

i dont get what you mean

OpenStudy (lyrae):

900 = (10x + 2) + 165 + 100 + (5x + 83) + ... 900 = 36x + 504

OpenStudy (anonymous):

oh ok

OpenStudy (anonymous):

so i slove 900=36+504 now

OpenStudy (lyrae):

yup

OpenStudy (anonymous):

x =11

OpenStudy (lyrae):

Correct!

OpenStudy (anonymous):

thanks for all your help and time

OpenStudy (lyrae):
