Answer:
m∠Q ≈ 53°
Step-by-step explanation:
To find the measure of ∠Q, the law of cosines will need to be used. Lowercase letters represent the side lengths, while upper case letters represent angles.
In this situation, 'A' will be ∠Q. Therefore:
17² = 18² + 20² -2(18)(20)cosQ
Simplify:
289 = 324 + 400 -2(360)cosQ
Continue simplifying down:
-435 = -720cosQ
Divide both sides by '-720':
0.604 = cosQ

m∠Q ≈ 52.83 or 53° rounded to the nearest whole degree.

Answer:
4280 passes were sold
Step-by-step explanation:
The unknown we are looking for the number of passes that were sold. We don't know how MANY were sold, but we do know that the cost of ONE is 12.50. We represent the number of passes at that price per pass as
12.50x
We also know that money earned from the sale of this unknown number of passes came to 53,500. Our equation then becomes
12.50x = 53,500
Solving for x, we divide both sides by 12.50 to get that
x = 4280
