Question

find the measure of the arc or angle indicated

Answer 1

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
