Answer:
b.168
Step-by-step explanation:
Sin C = AB / AC
We have AC. We need to calculate AB
ABC is a right triangle. Therefore, AC² = AB²+BC²
82² = AB ² + 80² => AB² = 82² - 80²
AB = 18
Sin C = 18/82 = 9/41
Good luck
the explanation and the answer in the photo
Aas i belive . If not consult the other answer
That is =
(42.1/100)*37.5
=(421/1000)*(375/10)
=(157875/10000)
=15.7875
=15.8
=16
