Answer:
AB = 4.41
Explanation:
cos theta = opposite / hypotenuse
We know theta = 25 and the opposite side =4
cos 25 = 4 / hypotenuse
Multiply each side by hypotenuse
hypotenuse * cos 25 = 4/ hypotenuse * hypotenuse
hypotenuse * cos 25 = 4
Divide each side by cos 25
hypotenuse * cos 25/ cos 25 = 4/cos 25
hypotenuse = 4/cos 25
hypotenuse = 4.413511676
Round to the nearest hundredth
hypotenuse = 4.41
