Answer:
-30, 210 and 330 degrees
Step-by-step explanation:
Given the expression Sin x = - 1/2
x = arcsin(-1/2)
x = -30 degrees
Since sin is negative in the third and fourth quadrant
x = 180 + 30
x = 210 degrees
In the fourth quadrant
x = 360 - 30
x = 330
Hence the value of x within the interval -360 < x < 360 are -30, 210 and 330 degrees
Answer:
B). 5.6
Step-by-step explanation:
3.2/x = 4/7
Then, cross-multiply
4x = (3.2) 7
4x = 22.4
x = 5.6
Answer:
y=2
Step-by-step explanation:
Multiply -3(2) which gives -6, -6+8=2
Thus, y=2
For this case we have that by definition, the slope of a line is given by:
Where:
and 
are two points through which the line passes.
According to the image we have:
Substituting we have:
Thus, the slope of the line is:
