Sense it tells you in the beginning that both shapes are similar you know that the angles are going to be the same so angle F has to be 120 Engel E has to be 85 angle D Hass to be 75 and angle C has to be 80. That should give you two of your answers already. Now to find line FE you need to figure out the difference between the shapes. I show you this in the picture below. All I did was use cross multiplication. And since you know that shape EFGH is smaller than shape ABCD. You know that 4 is most likely your answer because it’s smaller than 5.
