Answer:

m\angle EFG=52^{o}

Step-by-step explanation:

We have been given that line m is parallel to line p, m\angle HEF=39^{o} and m\angle IGF=13^{o}.

Since line m is parallel to line p and EJ is a transversal, so measure of angle EJG will be 39 degrees as angle EJG is alternate interior angle of angle HEF. Both angles are inside parallel lines m and p and on opposite side of transversal EJ.

We can see that angle EFG is exterior angle of triangle GFJ. Since the measure of an exterior angle of a triangle equals to the sum of the opposite interior angles.

We can see that angle IGF and angle EJG are opposite interior angles of angle EFG.

m\angle EFG=m\angle IGF+m\angle EJG

Upon substituting our given values we will get,

m\angle EFG=13^{o}+39^{o}

m\angle EFG=52^{o}

Therefore, measure of angle EFG is 52 degrees.
