Answer:
The angle with measure 60° is one of those angles that has a well-known cosine value: cos(60°) its C= 1/2.
Step-by-step explanation:
Answer: X < -3
Step-by-step explanation:
-15x - 3 > 42
-15x - 3 + 3 > 42 + 3
-15x > 45
-15x/-15 > 45/-15
Since we are dividing by a negative, we flip the >
x < -3
So, let's check
-4 < -3
-15*-4 - 3 > 42
60 - 3 > 42
57 > 42
Now, let's see if -3 will work.
-15*-3 - 3 > 42
45 - 3 > 42
42 > 42 (False)
Okay, now let's try 4
-15*4 - 3 > 42
-60 - 3 > 42
-63 > 42
This is false, so it is x < -3
