Answer:
X = 33
Angle K = 80
Angle J = 61
Step-by-step explanation:
All angles add up to 180
So, we can set it up like this:
39 + (-19 + 3x) + (x + 28) = 180
Now, we can solve:
48 + 4x = 180
4x = 132
x = 33
Therefore, x is equal to 33.
Check:
39 + -19 + 3(33) + 33 + 28 = 180
39 - 19 + 99 + 33 + 28 = 180
180 = 180
I hope this helps!!
