Question

What is the length of EF and the measure of D?

Answer 1

D is 37 since a triangle adds to 180, so you would do 90+53+x=180

Answer 2

So is it B?

Answer 3

I'm gonna go with A, not 100% positive but I did Pythagorean theorem on the second triangle and it came out that the bottom angle was like 9.6 so 10 if you round.
