I think that you would divide 6x by 2x so C. maybe
I hope this is right
If two angles are supplementary, their measures add to 180 degrees.
Let’s name the angles A and B.
You can substitute or replace angle B in the first equation with the second equation like so:
4
So, angle A is 42.5 degrees and angle B is 137.5 degrees!
Let's look at the second equation and try multiplying it by 4:
4 * (3x + ky) = 4 * 27
Which gives us:
12x + 4ky = 108
This looks almost exactly like the first equation except that instead of -20y, there is 4ky. We could try making them equal to each other and solving for k:
-20y = 4ky
-20 = 4k
k = -5
Then, the answer is k = -5.
16 is increased by 25% becoming 20. 4 is 25% of 16.
The line <em>AC</em> is a side that is common to both triangles.
Note: "Help" and "answer" are two different things.
