In order to answer that, I'd have to know the relationship between angle-2 and 'x'.
A drawing or a sketch would be a great way to explain that, if you had one. In fact,
if you'll take another quick look in the book or the homework sheet that you copied
the question from, I may be way out of line, but I'm guessing there's a little sketch
or drawing there, somewhere real near the question. Spend a few minutes looking
at it, and I'll just bet you might be able to answer the question on your own.
to find x in that way you need to have two measurements not just one
x is the angle you're looking for and 3x is the angle that when added to x must total 180 degrees. Therefore the angle is 45degrees (x + 3x = 180)

If it is a regular nonagon, then you use the following formula: [(s-2) x 180]/s = angle of one interior angle. (s means the number of sides) Then solve: [(s-2) x 180]/s = [(9-2) x 180]/9 = [7 x 180]/9 = 1260/9 = 140. Then, for the exterior angle, subtract 140 from 360. The measure of the exterior angle of a regular nonagon is 220.

Exterior angle = 360/45 ie 8o so interior angles are 172o. Check: ((90 - 4) x 90)/45 = 86 x 2 = 172.
The answer is 13. x=13 13*5+13*2=91 Thank you.

Suppose the angle is x then its supplement is 180 - x so 180 - x = x - 78 that is, 258 = 2x or x = 258/2 = 129 <><><><><> Angle + Supplement = 180 Angle = Supplement + 78 Solve for the system of equations... Angle + Supplement = 180 Angle - Supplement = 78 ------------------------------------- 2 Angle = 258 Angle = 129 Supplement = 51
1/2 x = 2 (180-x) x = 4(180-x) x = 720 - 4x 5x = 720 x = 144 degrees
144 degrees 1/2 x = 2 (180-x) x = 4 (180-x) x = 720 - 4x 5x = 720 x = 144
1 x 86, 2 x 43, 43 x 2, 86 x 1 = 86
x is the angle you're looking for and 3x is the angle that when added to x must total 180 degrees. Therefore the angle is 45degrees (x + 3x = 180)
1, 2, 43, 86 (1 x 86, 2 x 43).
90 - x = 1/2 (180 - x)2 (90 - x) = 180 - x180 - 2x = 180 - x180 - x = 180It looks like the only angle for which that's true is zero degrees.Complement of zero = 90Supplement of zero = 18090 = 1/2 of 180
x+y=180 y= x+38 x+(x+38)= 180 2x+38=180 -38 =-38 2x = 142 x= 71 plug it in equation 71+71+38= 180 angle 1 = 71 angle 2 = 109
