A person walks 25.0 degrees north of east for 3.80 km. How far would the person walk due north and due east to arrive at the same location? I did the Sin of 25 but the answer was wrong

You didn't solve for the north and east directions. It isn't sin 25, it's sin 25 = north/3.8 or 3.8*sin 25 = 0.423 x 3.8 = 1.61 km north.
cos 25 = east/3.8
3.8*cos 25 = 0.906*3.8 = 3.44 km east.
