Answer:

AC = 6.81

Explanation:

∠BAC = 90° - 27° = 63°

Cos 63° =
(AC)/(AB) = 0.454

AC = cos 63° * AB = 0,454 * 15 = 6.81

Answer:

B

Explanation:

side Ac is the opposite of angle B, therefore use the sin ratio to find ac since the hypotenuse is also given

sin B=opposite/hypotenuse

sin 27=ac/15

ac=sin27×15

=6.81

I hope this helps
