What is the measure in degrees of angle EDF?

EDF = 20

Step-by-step explanation:

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

EDF = 20

i think it is c, not positive though

step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
