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°

Answer:
92.5%
Step-by-step explanation:
shaded squares/total squares = 185/200
simplify:
(185/5)/(200/5) = 37/40
37/40= 35/40 + 2/40
32/40 + 5/40 = 4/5 + 1/8
4/5 + 1/8 = 0.8 + 0.125
0.8 + 0.125 = 80% + 12.5%
80% + 12.5% = 92.5%
Answer:
that depends
Step-by-step explanation:
how many students are in the school all together, see you would do the 3 boys over the number of people (or students) in the school
hoped this helped a little
