<PRE><B>Question 593657</B>
Find the angle (in degrees) between the two lines:
6x-y+8=0
-3x-11y+10=0
-------------
Find the slope of each:
6x-y+8=0
m1 = 6
------
-3x-11y+10=0
m2 = -3/11
------
The tangent of the angle between the x-axis and the line is the slope.
-----
tan(A) = 6
A =~ 80.54 degs
---
tan(B) = -3/11
B = -15.26 degs
diff = 96.8 degs
or 180 - 96.8 = 83.2 degs
