It looks to me like y = 4x + 1
You made a mistake with the probability 
, which should be 
in the last expression, so to be clear I will state the expression again.
So we want to solve the following:
Conditioned on this event, show that the probability that her paper is in drawer 
, is given by:
(1) 
and
(2) 
so we can say:
is the event that you search drawer 
and find nothing,
is the event that you search drawer and find the paper,
is the event that the paper is in drawer 
this gives us:
Solution to Part (1):
if 
, then 
,
this means that
as needed so part one is solved.
Solution to Part(2):
so we have now that if = , we get that:
remember that:
this implies that:
so we just need to combine the above relations to get:
as needed so part two is solved.
Answer:
( a ) 99°
( b ) 151°
Step-by-step explanation:
( a )
( 180 - 81 )° = 99°
( b )
( 180 - 29 )° = 151°

Answer;
C) The second arc should be centered at C.
Explanation;
Assuming the goal is to construct a line parallel to AB that passes through given point C.
-Draw a line through C and across AB at an angle creating D.
- With the compass width about half of DC, and center D, draw the first arc to cross both lines.
-Using the same compass width , draw the second arc with center C.
-Then set the compass width to the lower arc (the first arc)
- Move the compass to the second arc. Mark off an arc to make point E
-Draw a straight line through C and E
Thus the line CE will be parallel to line AB
