Answer:
Step-by-step explanation:
If slope of two lines are equal, then they are parallel lines.
If product of the slope of two lines is (-1), then they are perpendicular lines.
C) y = x + 2
Slope m1 = 1
y = -x + 3
Slope m2 = -1
m1 * m2 = 1 * (-1) = -1
These are perpendicular lines.
D) y = 3x + 2
Slope = m1 = 3
y = 3x - 2
Slope = m2 = 3
Slopes are equal. So, they are parallel lines.
E)y= 3
This line is parallel to x -axis.
x = 4
This line is parallel to y-axis.
So, both lines are perpendicular to each other.
F) y = x + 8
slope m1 = 1
y = -x + 3
Slope = m2 = -1
M1 * m2 = 1 * (-1) = -1
So, These are perpendicular lines
Answer:
Step-by-step explanation:
m∠1 = 2x and m∠2 = -3x+235
angle 1 and angle 2 are supplementary angle so they add up to 180°
m∠1 +m∠2 = 180°
2x -3x+235 = 180°
-x = 180-235
x=35
m∠1 = 2x = 2*35 = 70°
m∠2 = -3x+235 = -3*35 +235 = 235-105 = 130°

I really hope this helps! Look at the image I Uploaded.
(5+8)x(6-2)+5 The brackets go there because of the way the numbers are placed. (I added words because without them I could not post this answer.)
