2x+3+x+7+3x-5+2x-11= 180. (angle sun)
7x+ -6=180
7x= 186
7x+ -6=180
7x= 186

2x+3+x+7+3x-5+2x+11=360 (sum of 4 angles of a quadrilateral in 360)
8x+16=360
8x=344
x=43
Therefore measure of 1st angle=(2×43)+3=89
2nd angle=43+7=50
3rd angle=(3×43)-5=124
4th angle=(2×43)+11=97
8x+16=360
8x=344
x=43
Therefore measure of 1st angle=(2×43)+3=89
2nd angle=43+7=50
3rd angle=(3×43)-5=124
4th angle=(2×43)+11=97
