Answer:
m∠1= 31° m∠2=149°
m∠3= 31° m∠4=149°
m∠6=31° m∠7=149°
m∠8=31°
Step-by-step explanation:
m∠1 + m∠5= 180°
m∠1=180-149
m∠1=31°
m∠2+m∠1=180
m∠2=149°
m∠6=31°
m∠3=m∠1 (corresponding angle)
m∠3=31° m∠8=31° (vertical angle)
m∠4=149° m∠7=149° (vertical angle)
p=number of seashells pierre collected
p+3p=52
4p=52
p=13
13 seashells
10 percent of 51 is 5.1
1:2 by division of 5
10:9 by division of 6
