Find measure for firgure ABC?

Okay,
so far i have
(5x+8)+(6x+22)+(3x-25)=360
14x+5=360
14x=355
x=25.35
Now, as far as i can tell, that is correct. please tell me if its not.
In the figure, do A, B, and C represent the interior angles?

... so far i have

(5x + 8) + (6x + 22) + (3x - 25) = 360 The sum of the three interior angles in any given triangle is 180°, not 360°

... In the figure, do A, B, and C represent the interior angles? No. A, B, and C are vertex points, not angles.

These three interior angles are written as they appear at the top of your posted image. (The letter m is read as "the measure of the angle".)

We can also denote these interior angles in terms of the vertices as follows.

angle CAB

angle ABC

angle BCA

That fasteddie guy said it was 360 not 180. i am soo confused now. does x=12.5 or 25.35??

That fasteddie guy said it was 360 not 180 ... x = 12.5 or 25.35 ?

x = 25/2 (which, of course, is 12.5)

Please provide the link to the post where the incorrect value of 360 is stated, so that I may correct it.

PS: It is much easier to read typewritten mathematical expressions if you put spaces around the following characters: + - =

Lectro Magnet:

You were not paying attention. Fast Eddie said "exterior" angles, not "interior" angles.

But isnt the equation (5x+8)+(the rest...)=180
then 14x+5=175
14=12.5
??
or is it (5x+8)+(the rest...)=360
then 14x+5=355
14=25.35
??

But isnt the equation (5x+8)+(the rest...)=180 Why are you so lazy? Stop typing crap like "(the rest)".

then 14x+5=175 No, this is not correct. Clearly, you need to review basic algebra.

14=12.5 Clearly, these two numbers are not equal. (I did not believe you before, but, now, I think you really are sick.)

or is it (5x+8)+(the rest...)=360 I already answered your question about this error; clearly, you are NOT PAYING ATTENTION!

14=25.35 Good grief! You're suffering from delirium; go see a doctor, and after you're healthy, then come back ...

YOU ARE WASTING YOUR TIME AND MINE!
