Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40

Answer:
1,203,650,000 mi³
Step-by-step explanation:
Volume of a sphere is given by V = (4/3)πr³
in this case diameter D, = 1320 mi
radius, r = D/2 = 1320 / 2 = 660 mi
volume V, = (4/3)(3.14) (660)³
= 1,203,649,920 mi³
= 1,203,650,000 mi³ (nearest thousand)
D is the answerrrrrrrrrrrrrrrrrrrrrr
So easy y=1/5x cuz 20 times 1/5=4
