Answer:
<L+<M+<N=180
<NLM and <XLN are supplementary meaning their angle measure add to 180.
therefore,44+46+L=180
90+L=180
l=90
If l=90 then the <NLX is also 90 since they are supplementary angles
therefore, 3x+42=90
3x=48
x=16
Step-by-step explanation:
Answer:
J=16
Step-by-step explanation:
You have to move all the number to the opposite side of the variable.
j-12=4
j=4+12
j=16
