To answer your question:
0.5 is 10 times greater than 0.05
100 degrees I think....
I’m writing this because it said it was too short
The equation of the line is 
Step-by-step explanation:
The slope is 
Also, the line passes through the points 
To find a line with slope
that passes through the points
, let us use the equation of a line with slope that passes through the point is given by
where m is the slope and
are the points
.
Thus, substituting the values in the equation of a line, we get,

Multiplying the term
by -5, we get,

Adding both sides by 5x,

Subtracting 35 from both sides of the equation,

Thus, the equation of the line is 
∠ABC = 30 degrees
Since ∠DBC is its complement, ∠DBC = 90 - 30 = 60 degrees.
BE is the angle bisector of ∠ABD.
Therefore, ∠ABE = ∠DBE = 45 degrees.
Please refer to the attached figure.
So,
A. No
B. Yes
C. Yes
