Ineed answers for both of these u guys

A and e are congruent so e is 105 since h and e make a line they will add up to 180
180=105+h
H= 75
If the triangles are similar then
8~y and 6~9 divide 9 by 6 to get the scale factor this is how much the triangle enlarges by or shrinks by
9/6= 1.5 now that you know the scale factor you can find y y/8=1.5
Y= 12

Idon’t understand sorry
