180 x 13 = 2,340
234-180=54 54/234 x 100%= 300/13 or 23.1 (3s.f)
13/180 = 7.22%

w = 13 add 28 to 180, then subtract 13 from 180 to balance equation. Then 4w + 11 w = 195. Add 4w + 11w =15w, so 15w=180, divide 180 by 15, w = 13 4(13) -28 + 11(13) + 13 = 180
180 x 13 = 2,340
13 x 4 and 60 x 3
First off do X-2 then (X-2) x 180. There is your answer For example, 15-2 = 13 13 x 180 = 2340. so a 15 sided polygon has an angle sum of 2340.
234-180=54 54/234 x 100%= 300/13 or 23.1 (3s.f)
cot x = (cos x) / (sin x) cos (x - 180) = cos x cos 180 + sin x sin 180 = - cos x sin (x - 180) = sin x cos 180 - cos x sin 180 = - sin x cot (x - 180) = (cos (x - 180)) / (sin (x - 180)) = (- cos x) / (- sin x) = (cos x) / (sin x) = cot x
13/180 = 7.22%
The factor pairs of 180 are 1 x 180, 2 x 90, 3 x 60, 4 x 45, 5 x 36, 6 x 30, 9 x 20, 10 x 18, and 12 x 15.
3 x 60 = 180 4 x 45 = 180 5 x 36 = 180 6 x 30 = 180 9 x 20 = 180 10 x 18 = 180 12 x 15 = 180
60 of 180 = 60 x 180 = 10,80060% of 180 = 180 x 0.6 = 10860% off 180 = 180 x 0.4 = 7260 off 180 = 180 - 60 = 120
55 + x = 180 x = 180 - 55 x = 125
