Step 1: Find arc angle GJ
The sum of the arc angles of a circle is 360°.
Therefore,
![\begin{gathered} <p></p><p>step2: Find the angle GKJ, the angle subtended by the arc GJ</p><p>The angle GKJ is the angle subtended by the arc GJ at the center of the circle</p><p>Therefore,</p>[tex]<\text{GKJ }=\text{ m < GJ }=146^o]()
Step 3: Find m < GHJ
From Circle theorem, we know that the angle at the center of a circle is twice the angle at the circumference
Therefore,
[tex]\begin{gathered} <\text{GKJ }=2\times
Hence, m 73°Step 4: Find m < GIJFrom Circle theorem, the angles in the same segment are equalTherefore,[tex]<\text{GIJ }=Hence, m < GIJ = 73°
