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°

Jeremy got a haircut and paid 15% as a tip. What percent of the cost did Jeremy pay the barber, including the tip?
Bezzdna [24]

The percentage of the cost that Jeremy will pay including the tip paid is<u> 115% </u>of the cost.

Assuming the cost was $100 and Jeremy gave a 15% tip. The total he would pay is:

= 100 + tip

= 100 + (100 x 15%)

= $115

In percentage this is:

= 115/100 x 100%

= 115%

In conclusion, Jeremy would pay 115% of the tip.

Hit me up if ur bored but what's 7x-2y=23 squared
goblinko [34]
Simplify 7x + 2y = -23 Solving 7x + 2y = -23 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2y' to each side of the equation. 7x + 2y + -2y = -23 + -2y Combine like terms: 2y + -2y = 0 7x + 0 = -23 + -2y 7x = -23 + -2y Divide each side by '7'. x = -3.285714286 + -0.2857142857y Simplifying x = -3.285714286 + -0.2857142857y
