AC is opposite to the given angle, and CB is adjacent to that angle as its not opposite to the angle, or the hypotenuse. When opposite and adjacent are given, we use the tan to find the missing angle or side.
tan 25 degrees=opposite/adjacent
tan 25=AC/5
AC=5 x tan 25
AC= 2.3315 cm
To the nearest hundredth means up to two decimal places, which is two digits right to the decimal point. The answer will not be rounded up as the digit after the second decimal place is less than 5.
AC=2.33 cm.
