208 ÷ 13 = 16, so her rate is $16 per hour. Through guess and check,

Kira would have to work 11 hours to make $176.

Ok first lets find out how many she earns per hour. To find that out you must do 208/13 which equals 16. So Kira earns $16 per hour. Now you need to do 176/16 to find out how many hours she need to work to earn 176. it equals 11. So Kira need to work 11 hours to earn 176 dollars!! hope this helps pls mark me as the brainliest!!

Answer:

D. ( {x} - 2)^{2}  = 7

Step-by-step explanation:

3 {x}^{2}  - 12x = 9 \\ 3( {x}^{2}  - 4x) = 9 \\  {x}^{2}  - 4 x= 3 \\  {x}^{2}  - 4x + 4 = 3 + 4 \\  {x}^{2}  - 4x +  {2}^{2}  = 7 \\ ( {x} - 2)^{2}  = 7

Answer:

angle 1 = angle 7 = angle 9 = angle 15 and angle 3 = angle  5 = angle 11 = angle 13

Also,

angle 2 = angle 8 = angle 10 = angle 16 and angle 4 = angle 6 = angle 12 = angle 14

Step-by-step explanation:

Let suppose a and b are two parallel lines, and c and d be the transverse lines.  

The pairs of corresponding angles for a non-vertical line c are:

2-10, 7-15, 1-9, 8-16.

The pairs of corresponding angles for a non-vertical line d are:

4-12, 5-13, 3-11, 6-14.

Angles are formed at the intersection between the transverse lines and parallel lines. As the vertical angle is the opposite of the intersection. So, vertical angles are equal.

The pairs of vertical angles for a non-vertical line c are 1-7, 2-8, 9-15, 10-16

The pairs of vertical angles for a non-vertical line v are 3-5, 4-6, 11-13, 12-14

For transverse line c:

As the vertical angles are equal so the angles 1 = 7 = 9 = 15

As the corresponding angles are equal, so the angle ∠ 10 = ∠ 2 and the opposite of ∠2 is ∠8 which is vertical to ∠8 and vertical angles are also equal.

So, the angles 10 = 16 = 2 = 8 are also equal.

For transverse line d:

As the vertical angles are equal so the angles 3 = 5 = 11 = 13

As the corresponding angles are equal, so the angle ∠12 = ∠4 and the opposite of ∠4 is ∠6 which is vertical to ∠6 and vertical angles are also equal.

So, the angles 12 = 14 = 4 = 6 are also equal.

<u>LETS TAKE AN EXAMPLE</u>:

Let suppose the angle 1 is 110°

Since, vertical angle are equal. So, angle 7 will be also 110°.

Hence, angle 1 = 110° = angle 7

We also know that corresponding angles are equivalent. So,

angle 9 would also be equal to 110°, and as the opposite of angle 9 would also be equal to angle 9. So, the angle 9 and angle 15 have same angles.

So, angle 9 = 110° = angle 15

Hence, angle 1 = angle 7 = angle 9 = angle 15 will all be equal to 110°.

As, the angle 2 is the supplementary to this angle 1.

As the angle 1 is 110, so the angle 2 will be 70°  as they are supplementary to each other.

And if angle 2 is 70°, then its opposite angle will be equal to 8. As angle 2 and 8 are equal.

So, angle 2 = 70° = angle 8

As the corresponding angles are equal, so the corresponding of 2 will be the angle 10 which will be also equal to 70°, and the opposite of angle 10 is angle 16, which is again equal to angle 10.

So, angle 10 = 70° = angle 16

Hence:  angle 2 = angle 8 = angle 10 = angle 16 will be equal to 70°.

Since the transverse line d is parallel to c. So,

angle 1 = angle 7 = angle 9 = angle 15 which are equal to 110° will have same angles as of angle 3 = angle  5 = angle 11 = angle 13

So, angle 3 = angle  5 = angle 11 = angle 13 will also be equal to 110°

And,

angle 2 = angle 8 = angle 10 = angle 16 will which are equal to 70° will have same angles as of angle 4 = angle 6 = angle 12 = angle 14

So, angle 4 = angle 6 = angle 12 = angle 14 will be equal to 70°
