The measure of angles are
[tex]m < FHG= 42\\m < FEG= 21 \\[/tex]
Central angle :
Central angle is equal to intercepted arc.
Also, inscribed angle is equal to half of the intercepted arc.
From the given diagram ,
Central angle is angle FHG.
Given that measure of Arc FG = 42 degrees
Central angle = intercepted arc
Central angle is same as intercepted arc.
[tex]m < FHG= m (arc FG)\\m < FHG= 42[/tex]
Inscribed angle is equal to half of the intercepted arc.
To find inscribed angle , we divide the intercepted arc by 2.
[tex]m < FEG=\frac{1}{2} (arc FG)\\m < FEG=\frac{1}{2} (42)\\m < FEG= 21[/tex]
The following angles are
[tex]m < FHG= 42\\m < FEG= 21 \\[/tex]
