Answer:

C x=17

Step-by-step explanation:

The top and bottom sides have to be equal for the quadrilateral to be a parallelogram

2x-9 = x+8

Subtract x from each side

2x-9-x = x+8-x

x-9 = 8

Add 9 to each side

x-9+9=8+9

x=17

➷ Opposite lengths in a parallelogram are equal

Therefore:

2x - 9 = x + 8

Add 9 to both sides:

2x = x + 17

Subtract x from both sides:

x = 17

Your answer is option c.

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°

a used car salesperson receieves a commission of 1/12 of the sales price of the car for each car he sells. What would the sales
Umnica [9.8K]
In this question, there are numerous important information's that needed to be taken note of. It is already given that 1/12 is the commission received by the salesman on the sales price of a car.
Then
Sales commission of the salesman on the car = (1/12) * 21999
                                                                           = 21999/12
                                                                           = 1833.25 dollars
So the salesman receives a commission of $1833.25 on the sales of the car that was priced at $21999. I hope you have understood the method by which the problem has been solved.
