3 would be 53. Since the lines are parallel the angles will be the same
4 would be 47 because of outer exterior angles
Answer:

Step-by-step explanation:
(1) A typical form of equation of a line is:

with,
is slope and
is y-intercept.
(2) Another straight line has equation in form of:

with
is slope and
is y-intercept
(3) If these two lines are perpendicular, according to the property of two perpendicular lines on the two-dimensional plane, we have:
x
= -1
(4) Transform the given equation of original line into typical form:

<=> 
<=> 
<=> 
=> 
=> 
=> Option D:
is correct (Slope =
)
