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=

so x =42
Let me know if you have any questions.

Step-by-step explanation:
Answer:
5 should be subtracted from each term
Step-by-step explanation:

Cross multiply,
1 * (11 - x) = 2*(8-x)
11 -x = 2*8 - 2*x
11 - x = 16 - 2x
Subtract 11 from both sides,
-x = 16 - 2x - 11
-x = 5 - 2x
Add 2x to both sides
-x +2x = 5 - 2 + 2x
x = 5

Answer:
30
Step-by-step explanation:
Just insert the value of x into the equation.
x = 3 right?
6^2 + 3 - 3^2 because x = 3
36 + 3 - 9 = 39 -9 = 30
