Answer:
B. 23 deg. 19 min.
Step-by-step explanation:
sin(x) = 0.39581
use the calculator (sin‐¹) and you get
x = 23.31650126...°
so, the correct answer must be B, as none of the others have 23° as part of the solution.
FYI
to get the minutes :
as 1° has 60' (one degree has 60 minutes), the first 2 decimal places after the decimal point (31) represent 31/100 of 60 minutes :
31×60/100 = 31×6/10 = 186/10 = 18.6 minutes ≈ 19 minutes.
