Answer:
Step-by-step explanation:
As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:

So, it's useful to solve the equation too, in order to verify the result:

Taking the inverse sine of both sides:

Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:

Answer: A And B
Step-by-step explanation:
Answer:
35
Step-by-step explanation:
When the two lines being crossed are Parallel Lines the Consecutive Interior Angles add up to 180°.
So, x + 12 + 4x - 7 = 180.
5x + 5 = 180
5x = 175
x = 35
