Answer:

Step-by-step explanation:
<u>Use the formula:</u>

<u>Plug in the numbers (coordinates) given, like so:</u>


<u>Simplify:</u>

Sec x = 1/Cosx
Pi radians = 180 degress
Pi/12 = 180/12 = 15 degrees.
Sec15° = 1/Cos15°
Sec pi/12 = Sec 15° = 1/Cos 15°
Cos 15° = 0.9659 using a calculator.
Sec pi/12 = Sec 15° = 1/Cos 15° = 1/0.9659 = 1.0353
Sec Pi/12 = 1.0353
Answer:
The answer is an obtuse angle
Step-by-step explanation:
Anything over 90 degrees is obtuse. Anything below 90 is acute and if is exactly 90 it is a right angle
To find out how many hours he worked you would do $120 divided by $8 which will give you 15 hours. So, your equation would be $120/ $8= 15
