A:
Problem 1
Answer: side AC
---------------
Explanation:
Side AC is opposite angle B because it is the furthest you can get on the triangle to be away from point B. This segment is a leg of the right triangle. Note how the letter B is not anywhere to be found in AC.
=========================================== Problem 2
Answer: 4/3
---------------
Explanation:
angle D is the right angle, the side across from this right angle is the hypotenuse EF
with reference angle F, we have opposite = ED = 4 adjacent = DF = 3
