A straight line has a degree of 180 degrees.
So you are trying to find the angle that is created with the points j,m, and l.
so take the other angle 54 degrees and subtract that by 180.
180-54=126 degrees.
so now that you have the angle of J,M,L set that to equal 3x
3x=126
divide 3 from both sides
x= $\frac{126}{3}$
so x =42

Let me know if you have any questions.

Distance between two points <br> (-5,5) and ( 3,-3)

stiks02 [169]

Answer:

$8\sqrt{2}$

Step-by-step explanation:

Using the pythagorean theorem, you can find that the distance between the two points is $\sqrt{(3-(-5))^2+(5-(-3))^2}=\sqrt{128}=8\sqrt{2}$ . Hope this helps!
