sum of the angles =180° 2x+4x+7+3x+2=180° 9x+9=180° 9(x+1)=180° x+1=180°/9 x+1=20° x=20°-1 x=19° so, 1st angle=2x=2*19=38° 2nd angle=4x+7=4*19+7=83° 3rd angle=3x+2=3*19+2=59° Good luck !
3x + 4x + 2x = 180
9x = 180
x = 180/9
x = 20
You add the 3,4,and 2 together to get 9x. Then Divide 180 by 9. Thus, x=20 (:
x = 180/9 = 20

3(20)+4(20)+2(20)=180
60+80+40=180
2x 3x 4x
Trial and error. Just keep adding numbers in for x until you find one that comes out to 180 for your answer.
: ) hope i helped.
