As both and
determine terminal points in the fourth quadrant, we know that both angles fall between
and
. We also know that
for
, and that
is strictly increasing along this interval.
This means that the angle with the larger cosine value must be closer to having a measure of 360 degrees than the angle with the smaller cosine value, so .
Answer:
y= (1/4)x+2
Explanation:
Comparing y =-4x + 8 to the slope-intercept form y=mx+b
• Slope = -4.
Let the slope of the new line = m
Two lines are perpendicular if the product of their slopes is -1.
Therefore:
The slope of the perpendicular line = 1/4
Since the line passes through the point (8,4), we have:
The equation of the perpendicular line is y= (1/4)x+2
