An equation is formed of two equal expressions. The given equation is not true.
<h3>What is an equation?</h3>An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The complete question is: Check whether the given equation is true or not?cos2pi/7+cos4pi/7+cos8pi/7=1/8.
To know if the given equation, is true or not, both the sides of the equation are needed to be solved separately.
The value of when simplified is equal to -0.5, or the value can be written as -(1/2).
Since the right side of the equation is equal to -1/2, while the right side of the equation is 1/8. Thus, the given equation is not true.
Hence, the given equation is not true.

Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)
Perpendicular lines always have slopes that are negative reciprocals. For example, 2 and -1/2. 3/4 and -4/3.
To determine whether a line is perpendicular to , we must first determine its slope. Rearrange the given equation into slope-intercept form:
From this, we can clearly tell that the slope (<em>m</em>) of the line is .
The negative reciprocal of is 2. Therefore, the slope of a perpendicular line would be 2.
Therefore, the correct answer option would be .
I hope this helps!
