Answer this question

Answer 1

XEF =EGH=80

EGH+HGY=180
80+HGY=180
HGY=100------1
SHY+GHY=180
120+GHY=180
GHY=60--------2
HGY+GHY+GYH=180 (SUM OF ALL ANGLES IN TRIANGLE IS 180)
100+60+GYH=180
160+GYH=180
GYH=20

Answer 2

angle 1 degree is equal to the angles g because of the corresponding angle and then by linear pair we will find the angle opposite to it that is hundred degree and another angle 120 - 180 is equal to 60 degree and then by angle sum property we will find the angle A that is 20 degree
