Step 1: Convert
, which is in radians into degrees. To convert it multiply by 

900/12
75
Step 2: 75 degrees isn't on the unit circle but 45 degrees and 30 degrees is. Since 45 + 30 = 75 you can use the cosine of 45 and 30 to find the exact value
cos45 = 
cos30 =
Step 3: Add the cos45 and cos30 to get cos5pi/12

Hope this helped!

Answer:
100+15p < 25p
Step-by-step explanation:
Note that
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
total cost of travelling = cost to rent a bus + total cost of ticket for p persons
100 + 15p
they want to spend less than an average cost of 25 per p people
they want to spend less than 25p
since they dont want to spend less than 25p, < would be used
100+15p < 25p
