Answer :
Answer:[tex]313^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle {EFG}=133^{\circ }[/tex]
When rotated 180 degree clockwise gives E'F'G' which measures
[tex]\angle E'F'G'=180^{\circ}+133^{\circ}=313^{\circ}[/tex]
This can be explained by the below-given digram

Rotation is a rigid transformation.
The measure of angle E'F'G' is 133 degrees
Because rotation is a rigid transformation, it does not change the side lengths and the angle measures.
This means that the measure of angle EFG will remain unchanged after rotation.
i.e.
[tex]\mathbf{\angle E'F'G' = \angle EFG}[/tex]
Hence, the measure of angle E'F'G' is 133 degrees
