For this case we have that by definition, it is called arcsine (arcsin) from a number to the angle that has that number as its sine.
We must find the 
. Then, we look for the angle whose sine is 
.
We have to, by definition:
So, we have to:
Answer:
Option B
Answer:
8 23/40
Step-by-step explanation:
8 and 5 have 40 in common. To get from 8 to 40 you need to multiply by 5. You have to do the same to the top and bottom numbers in the fraction. 3/8 turns into 15/40. To get from 5 to 40, you need to multiply by 8. Again, u have to do the same for the top and bottom. 1/5 turns into 8/40. 15/40 + 8/40 = 23/40. Add the whole numbers, 6 and 2, to get 8. So the answer in 8 23/40. Hope this helps!
