cot(<em>x</em>) = cos(<em>x</em>) / sin(<em>x</em>)
so
cos(<em>x</em>) / cot(<em>x</em>) = 1 / (1/sin(<em>x</em>)) = sin(<em>x</em>)
Then
sin²(<em>x</em>) + sin(<em>x</em>) cos(<em>x</em>) / cot(<em>x</em>) = sin²(<em>x</em>) + sin²(<em>x</em>) = 2 sin²(<em>x</em>)
The equation x = -8 contains the two points (-8 , -3) and (-8 , 1) ⇒ 2nd answer
Step-by-step explanation:
Let us revise the equations of the horizontal and vertical lines
- The equation of a horizontal line passes through point (a , b) is y = b, because all points lie on the line have the same y-coordinate b
- If a line passes through two points have the same y-coordinates, then the line is horizontal
- The equation of a vertical line passes through point (a , b) is x = a, because all points lie on the line have the same x-coordinate a
- If a line passes through two points have the same x-coordinates, then the line is vertical
∵ The line contained the two points (-8 , -3) and (-8 , 1)
∵ The two points have the same x-coordinate = -8
- From the 4th note above
∴ The line is vertical
∵ The equation of a vertical line is x = the x-coordinate of any point
on the line
∵ The x-coordinate of the points on the line = -8
∴ The equation of the line is x = -8
The equation x = -8 contains the two points (-8 , -3) and (-8 , 1)

Answer:
x=4
Step-by-step explanation:
Hey there!
I am going to use this image as an example so you can understand the formula
The formula for problems like these is
B(BA)=D(DC)
So all we have to do is plug in the numeric values
so now we have 5(5+x+3)=6(6+x)
now we just solve for x
5(5+x+3)=6(6+x)
step 1 distribute the 5 to what is in the parenthesis (5, x and 3)
5x5=25
5*x=5x
5x3=15
so now we have
25+5x+15=6(6+x)
step 2 distribute the 6 to what is in the parenthesis (6 and x)
6x6=36
6*x=6x
now we have
25+5x+15=6x=36
step 3 combine like terms, the only like terms are 25 and 15
15+25=40
now we have
40+5x=6x+36
step 4 subtract 5x from each side
5x-5x cancels out
6x-5x=x
now we have
40=x+36
step 5 subtract 36 from each side
40-36=4
36-36 cancels out
now we have
x=4 so we can conclude that x=4
hope this helps :)
