1) Yvonne buys gloves that cost $10.00. At the register, she must pay $10.80. ⇒ EXCISE TAX
2)Sasha bought a house last year. She just got a tax bill from the county showing the value of her house and the amount of tax. ⇒ PROPERTY TAX
3) Bigmart sells boots made in China and boots made in the U.S. Bigmart must pay 27% tax on each pair of boots made in China, but not on the U.S. made boots. ⇒ TARRIFF.
4)State citizens voted to add a 75-cent tax to each pack of cigarettes to pay for programs to help people quit smoking. ⇒ SALES TAX
5)Jake got his paycheck today. He worked 40 hours at $20 per hour His gross pay was $800, but the amount of his paycheck was only. ⇒ Income/Social

According to the information given, the ramp would be 50 feet high. (However, that seems really high. Did you type your problem correctly?)
If you draw a picture, you will see that you can set up a cosine ratio to solve this problem. With a 30 degree angle of depression, the angle we are going to use 60 degrees.
We can set up the following equation:
cos(60) = x / 100
0.5 = x / 100
50 = x
Answer:
28. 120 degrees
29. 30 degrees
30. 56 degrees & 124 degrees
31. 72 degrees, 108 degrees, and 18 degrees
Step-by-step explanation:
We assign variable x for the answer we are looking for (28-29).
28.
Supplement means x + y = 180 degrees. We also know x = 2y. Substitution gives us 3y = 180 degrees, so y = 60 degrees and x = 120 degrees.
29.
Complement means x + y = 90 degrees. We are given 2x = y. Substitution brings us 3x = 90 degrees, x = 30 degrees.
30.
Supplement means x + y = 180 degrees. We are told that y = 2x + 12, so we substitute. This gives 3x + 12 = 180 degrees, x = 56 degrees. Substituting that back into the equation for y, we get 124 degrees.
31.
Supplement means x + y = 180 degrees. Complement means x + z = 90 degrees. Using our given info, we know y = 6z. We can substitute that in to get x + 6z = 180. Subtracting our second and third equations, we get 5z = 90, z = 18 degrees. Therefore, x = 72 degrees, y = 108 degrees.
