the angle formed <lkj is formed by two tangents intersecting outside of circle so the rule is
<lk j= (m.JML - M. LJ ) divided by 2
2 (45x +2) = m.JML - (132x +1 )
90 x + 4 = m.JML -132x-1
m.JML = 90x + 4 + 132x +1
m.JML = 222 x +5
we have in the given m.JML = 229x -2
229x -2 = 222 x +5
7 x = 7
x= 1
m.JML = 229x -2
we replace the x by 1
m.JML = 229x -2 - 229-2= 227
