Answer: 5.625
Explanation:
why are yall doing triangles...
oh well. for this, you'll need sin law
because you only have one side and you need to find the hypotenuse
a = 180 - 25 - 90
a = 65'
SinB SinC
--------- = ----------
b c
65 90
---------- = ------------
4 c
64c = 90(4)
64c = 360
c = 360/64
c = 5.625
c is also the same thing as saying AB
