Answer:
The equation of the perpendicular line is 2 x + y + 1 =0
Step-by-step explanation:
<u><em>Step(i) </em></u>:-
Given equation of the line 2y = x - 18
x - 2y - 18 =0
The equation of the perpendicular line to the given line
b x - ay +k=0
-2 x - y + k =0 this line is passing through the point ( 0 , -1)
⇒ 0 -(-1) + k=0
⇒ 1+k =0
⇒ k = -1
<u><em>Step(ii):-</em></u>
The equation of the line is perpendicular to the line
-2x - y - 1 =0
2 x + y + 1 =0
<u><em>Conclusion:-</em></u>
The equation of the perpendicular line to the given line 2 x + y + 1 =0
Answer:
x = 69 degrees
Step-by-step explanation:
180 - 146 = 34
180 - 77 - 34 = 69
x = 69 degrees
Answer:
The value of y is 3.
Step-by-step explanation:
Given points: P(12,-2), Q(5,-10), R(-4,10) and S(4,y).
We need to find the value of y so that line PQ is perpendicular to line RS.
Slope formula:
Slope of PQ is
Slope of RS is
The product of slopes of two perpendicular lines is -1.
Add 10 on both sides.
Therefore, the value of y is 3.
