Answer:
21.8
Step-by-step explanation:
We will use the property :
sum of interior angles on same side of transversal =180
(8x-14) + (2x+54)=180
10x+40=180
10x=140
x=14
-5/2
an example of how to write it is :)
Answer:
Step-by-step explanation:
X^2+7x+63=63
<=> x^2+7x=63-63=0
<=> X(x+7)=0
<=> x1=0
X2=-7
Slope of a line parallel to given line is equal to slope of given line.
<u>SOLUTION:</u>
Given that, we have to find the slope of any line that is parallel to a line in the co – ordinate plane.
We know that, slope of a line is tan( angle of a line made between that line and the x – axis)
So, consider two lines which are parallel , then, angles made by both the parallel lines will be equal with the x – axis.
Then, tan( angle by 1st line) = tan( angle by 2nd line)
Which means that, slope of two lines will be equal.
Hence, slope of a line parallel to given is equal to slope of given line.
