7x-1+7x+8+5x+2=180
7x+7x+5x+2-1+8=180
19x+9=180
19x=180-9
19x=171
19x\19=171\19
x=9
therefore,7x-1
7(9)-1
=62
therefore, 7x+8
7(9)+8
=71
therefore 5x+2
5(9) +2
=47
Answer:10.1
Step by step explanation:
Round up to ten
6 rounds up so it’s just 10.1
X=14. The angles are supplementary, meaning they both add up to 180, so you would subtract 96 from 180, getting 84. X + 5x = 6x, so you would divide 84 by 6 to get 14. Therefore, x=14.
