Answer:

Step-by-step explanation:

Well, first of all the two angles listed on the diagram are alternate exterior angles. Since they are alt exterior angles, they must be congruent to one another. Congruent means: equal or the same.

1. So first I am going to form an equation.

(9x - 5) = (7x - 25)

2. Then I am going to solve.

(9x - 5) = (7x - 25)

3.  First, I am going to add 5 from both sides and solve.

(9x - 5) = (7x - 25)

      +5           +5

--------------------------

     9x = 7x - 30

4. Now I am going to subtract 7x from both sides.

  9x = 7x - 30

  - 7x   -7x

---------------------

  2x = 30

5. I am going to divide 2 from both sides, thus making x = 15

2x - 30

÷ 2   ÷ 2

--------------

x = 15 ( This is x, now all you have to do is plug this into each identified angle.

So, the first identified angle is  130 degrees

The second one is  also 130 degrees.

Remember, they are congruent so they have the same number (degrees

A sofa that cost $570 has 7.5% sales tax. Calculate the amount of sales tax a customer has to pay to buy the sofa?
Vera_Pavlovna [14]

Answer:

Total: $612.75

Tax amount: $42.75

Step-by-step explanation:

divide 7.5 by 100=0.075

0.075+1= 1.075

multiply that by 570=612.75

to find tax amount, subtract 570 from 612.75

BOOM!

Simple as that.
