Does anyone know the answer?

Answer:
AB = 4.41
Step-by-step explanation:
→You are given the adjacent side and need to find the hypotenuse. For this, we use cos.
→Set it up, like so:
[tex]cos25=\frac{4}{x}[/tex]
→To get rid of the x in the denominator, multiply everything by x:
[tex]x(cos25=\frac{4}{x})[/tex]
[tex]xcos25 = 4[/tex]
→Divide both sides by cos25:
x = 4.413
→Round to nearest hundredth:
x = 4.41
