JK and JL are opposite rays and ray JM bisects angle KJL. if m angle MJK = (5x+15) degree, find the value of x.
@dude

Do we have a picture for this one
no
Did you draw it out?
im so confused with this and one other so no.
Lets start with this: |dw:1539311969228:dw| That is what 'opposite rays' look like
Does that make sense?
well, i figured that much but then the nxt part of that sentence confused me so bad that i thought that the opposite rays are drawn differently
Quick question, do you know the angle of a straight line?
180?
Correct
Do you know what bisect means?
two cut in half
Then this should all make sense in a few moments.
So far we have 'JK and JL are opposite rays' drawn out. Lets focus on the next part which is: 'ray JM bisects angle KJ' |dw:1539312251715:dw|
'if m angle MJK = (5x+15) degree' Where is this angle on that picture. You can click the pencil in the top right corner of my drawing to draw on it.
|dw:1539312344512:dw|
Correct. What do you think the measure of that angle is?
Let me know if you need a hint. But just try and see if you can get it yourself.
90
Correct. Segment KL is perpendicular to segment JM. When lines are perpendicular, they create 90 degree angles.
Knowing that the angle is 90 degrees, what do you think you can do next?
Remember, the goal is to find the value of x
90=5x+15
Correct. You know how to do that right?
yes..
Okay cool
