Answer 1

Angle m∠8 =41° and x=10°

Step-by-step explanation:

Given that m∠3=139° then

m∠3=m∠1 = corresponding angles = 139° and m∠7=m∠5=m∠3=139°

m∠8= 180°-139° =41° -sum of angles on a straight line

m∠8=m∠6=m∠4=m∠2= 41°

2.

Given that m∠3=8x+70° and  m∠8=4x-10° then you can find the value of x as;

m∠3+m∠8=180°

8x+70°+4x-10°=180°

12x+60°=180°

12x=180°-60°

12x=120°

12x/12 =120°/12

x=10°

Hence,

m∠3=8x+70° = 8*10 +70° = 80°+70°=150°

m∠8= 4x-10° = 4*10 - 10° = 40°-10° =30°

m∠1 =m∠3 = m∠5 = m∠7 =150°

m∠2 = m∠ 4 = m∠6 = m∠8 =30°
