Answer:

1. 1=18°, 2=90°

2. 1=85°

3. 1=97°

4. 2=83°

5. 3=49°

6. 1=94°

7. 4=45°

8. 3=65°

9. 2=79°

10. 5=73°

11. 6=147°

12. 1=26°

13. 2=32°

Step-by-step explanation:

1. all angles of a triangle equal 180. 2 is 90 degrees because you can look across to find the symbol. Then you subtract 180 by 72 and 90 to get 18.

2. do the same thing as last time, 180 minus 40 and 55.

3. In order to figure this out, you need to have the angle 2. One you have 83, angles like this, together will add up to 360 if you put 2 of them together. 83×2=166. 360-166=194. 194/2=97.

4. To figure this out, you find the angle across from it because those are always the same. Follow the same process to subtract 39 and 58 from 180 to get 83.

5.Now that you have the angle 2 you can figure this one out as well, again, follow the process of subtracting the two opposite angles from 180 to get 49.

(This is taking really long to explain so if you have questions just ask.)

Answer:

{x}^{2}  + 3x

Step-by-step explanation:

1.

Area of shaded region = Area of external rectangle - Area of internal rectangle

= 4x(x + 2) - x(3x + 5) \\  = 4 {x}^{2}  + 8x - 3 {x}^{2}  - 5x \\  = 4 {x}^{2}  - 3 {x}^{2}  + 8x - 5x \\  =  {x}^{2}  + 3x \\

2.

Let the width of the rectangle be x inches.

Therefore, length of the rectangle = (x + 3) inches

A.

Area of rectangle

=(x + 3)\times x\\=x^2 + 3x\\

B.

Width of rectangle = 4 inches

Length of rectangle = 4 + 3 = 7 inches

Area of rectangle = 7*4 = 28 square inches.

Gennadij [26K]
This can be accomplished using addition. If time starts at 5:47, and it takes 33 minutes to get from Point Pleasant to Long Branch, then it is now 6:20. 
After you arrive, you waited 14 minutes. It is now 6:34. Finally, it's an hour and 20 minute journey from Long Branch to New York. The final time is 7:54. 

Hope this helps!

Svetllana [295]

Answer:

Step-by-step explanation:

1) Price of 8 pack of toothbrushes = $ 18.12

Price he paid after using coupon  = 18.12 - 3  = $ 15.12

Unit rate = Price he paid ÷ number of toothbrushes

              = 15.12 ÷ 8

              = $ 1.89

2) 0.5 hours = 30 minutes

Duration of guitar class on Monday = 30 minutes

Duration of guitar class on Tuesday = 1.5 hours = 1 hr 30 min

Duration of guitar class on Thursday = 2 hrs

Total duration  = 30 min + 1hr 30 min + 2 hrs

                         = 4 hrs

Amount paid for 4 hrs = $ 180

Rate per hour = 180 ÷ 4

                       = $ 45
