Answer:
Ans A). The graph is shown.
Ans B). 18.3333 C temperature when F is 65 temperature
Ans C). 32 F when the line crosses the horizontal axis
Ans D). Slope of line C=
is 
Step-by-step explanation:
Given equation is C=
Ans A).
For the table,
Take the four value of F as 32,41,50,59.
For F = 32.
The value of C is
C=
C=
C=0.
For F = 41.
The value of C is
C=
C=
C=05
For F = 50.
The value of C is
C=
C=
C=10
For F = 59.
The value of C is
C=
C=
C=15
<em>Note: The figure shows a graph of given equation with points.</em>
Ans B). Estimate temperature in C when the temperature in F is 65
For F = 65.
The value of C is
C=
C=
<em>C=18.333333.</em>
Ans C). At what temperature, graph lien cross the horizontal axis
When the line crosses the horizontal axis, C=0
Therefore,
C=
0=
0=
F=32 Temperature.
Ans D). Slope of the line C=
The slope of line is given by s= 
Take points from the table of answer A.
let (32,0) and (41,5) using for slope.
s= 
s= 
s= 
Slope of line C=
is 
Answer:
angles of the triangle are equal 180
so 42+82=124
180-124=56
so the answer is 56
