the answer is A)34. this is because angle G is congruent to the angle labeled 34, so they are both 34 degrees. let me know if you want a more in depth explanation
line P is parallel to line r and angle 34 degree is corresponding to angle H so angle H will be 34 degrees. Now angle H and G are vertically opposite to each other so angle G should be 34 degrees. Option A is correct. Hope it helps.
