cos(5x) + cos(2x) = 0
(5x)
cos * 5x + cos(2x) = 0
</span> 5cos * x + cos(2x) = 0
Multiply cos * x
5cosx + cos(2x) = 0
(2x)
5cosx + cos * 2x = 0
5cosx + 2cos * x = 0
Multiply cos * x
5cosx + 2cosx = 0 5cosx + 2cosx = 7cosx
7cosx = 0
Solving
7cosx = 0
Solving for variable 'c'. cosx = 0
Simplifying
cosx = 0
Hope this helps!
In short your answer is 0

Answer:
EQUATION OF LINE PERPENDICULAR
EQUATION OF LINE PARALLEL
We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
Answer:
R=155°
S=25°
T=155°
Step-by-step explanation:
R + 25° =180°
R = 180° - 25°
R = 155°
(2) S + 155° =180°
S = 180° - 155°
S = 25°
T = R because t is opposite of r
