Question

Which angle has the same measurement as angle DEA, and how do you know that the measurement is the same?

Answer 1

I don't know the exact answer but the correct answer would be A(Then, unknown value)E I think.

Explanation:

The reason why is because it would make a square if you put the answer and ADE together.

THIS COULD BE WRONG

Answer 2

The answer would beDEA or AED, they are both the same. If you extend the two lines like I did, you can tell they are parallel. Angle C and angle A on ADE are congruent because they are corresponding, right angles are equal, so you are left with E and A on triangle ABC.
