Question

Help with Finding the Angle Between Two Lines

Answer 1

Find the angle between the following two lines:



2x + 3y = 5

x − 3y = 6

Answer 2

3y=-2x+5
y=(-2x+5)/3
y=-2/3x + 1.7




3y=-x+6
y=(-x+6)/3
y=-1/3+2

Answer 3

tan^-11(-2/3)

180+tan^-1(-1/3)

@freckles does this look right so far?

Answer 4

ok I'm here finally after constant loading

Answer 5

one sec let me look at your problem

Answer 6

-33.7

180+-18.4

Answer 7

161.6-(-33.7)

Answer 8

also i meant ^-1 not -11

Answer 9

2x + 3y = 5

x − 3y = 6

=======

3y=-2x+5
y=-2/3*x+5/3



x-3y=6
-3y=-x+6
y=1/3*x-2


and let's see also where do they intersect

1/3*x-2=-2/3*x+5/3
x-6=-2x+5
x+2x=5+6
3x=11
x=11/3

so @x=11/3 we have y=1/3*11/3-2=11/9-2=(11-18)/9=-7/9

so the intersection is (11/3,-7/9)

so this graph looks like this:


so which angle are we talking about I wonder

Answer 10

oh dang it... I didnt cancel the negatives in the second one

Answer 11

or multiply them properly more so lol

Answer 12

I think I will look here
and see if I can find those two angles at the intersection of both of those right triangles
