in right triangle ABC, C is the right angle. Given measure of angle A = 40 degrees and a =6, which of the following are the lengths of the remaining two side, rounded to the nearest tenth?

tan 40° = 6 / AC
AC = 6 / tan 40°
AC = 6 / .8391
AC = 7.15

AB² = 6² + 7.15²
AB² = 36 + 51.123
AB² = 87.12
AB = 9.33
