Answer:
m∠B = 141°
Step-by-step explanation:
sides of polygon (n) = 7
sum of angles of polygon = {(n - 2) * 180°}
= {(7 -2)*180°}
= 5* 180°
= 900°
Now,
m∠B = 900° - 148° - 142° - 130° - 129° - 120° - 90°
m∠B = 141°
D because added up is 109 times 1.06 = 115.54 + the $5 shipping makes the answer $120.54
<u>Answer</u>
1st number = x
2nd number = 4x
3rd number = x + 100
sum of three numbers = 592
x + 4x + x + 100 = 592
6x + 100 = 592
6x = 592 - 100
6x = 492
x = 492/6
x = 82
1st number, x = 82
1st number, x = 822nd number, 4x = 328
1st number, x = 822nd number, 4x = 3283rd number, x+100 = 182
check :
82 + 328 + 182 = 592
