∠JKM =
and
∠JKM =![74\textdegree](/tpl/images/0076/1074/f7005.png)
Step-by-step explanation:
Since we have given that
∠JKM=10y+6
∠MKL=8y-6
Since they are linear pairs ,
So,![10y+6+8y-6=180\textdegree \\\\18y=180\textdegree \\\\y=\frac{180\textdegree}{18\textdegree}\\\\y=10\textdegree](/tpl/images/0076/1074/69a8e.png)
∠JKM =![10\times 10+6=100+6=106\textdegree](/tpl/images/0076/1074/8fca7.png)
and
∠MKL =![8\times 10-6=80-6=74\textdegree](/tpl/images/0076/1074/0f20a.png)
