Alright listen to the key words in the question specifically “CORRESPONDING” if u don’t know what corresponding means it means very similar or equivalent in comparison I will help u with the first 2 for u the corresponding Angle to a is angle x. ur basically looking for the same angle on 2 different triangles and the answer to angle b is angle z and if it’s 2 letters it means it one of the sides or lines to the triangle so line ab would be line xz on the other triangle I hope this helps
