Answer:
20 degrees.
Step-by-step explanation:
Since these triangles are similar, they will have congruent angles.
Since BAC is corrosponding to EDF, they will have the same angle measurment.
BAC = 20, so EDF = 20
EDF = 20
If the triangles are similar, the angle measurements have to be equal
<A = <D
<B = <E
<C = <F
Since BAC = 20, <A = 20 that means D = 20
