x = 36.2 .
______________________________________________
Explanation:
________________________________________________
2x - 1 + 3x = 180 ;
Combine the "like terms" on the left-hand side of the equation:
________________________________________________
+2x + 3x = + 5x ;
_____________________________________
And rewrite:
_____________________________________
5x - 1 = 180 ;
_____________________________________
Add "1" to each side of the equation:
_____________________________________
5x - 1 + 1 = 180 + 1 ;
_____________________________________
5x = 181 ;
_____________________________________
Divide EACH SIDE of the equation by "5" ;
_____________________________________
5x / 5 = 181 / 5 ;
_____________________________________
to get:
_____________________________________
x = 36.2 .

Answer:
10641.777 feets
Step-by-step explanation:
To obtain the distance to be traveled across the sea, we use trigonometry :
Cosθ = adjacent / hypotenus
Adjacent = 10000
Hypotenus = d
θ = 20°
Cos 20° = 10000 / d
0.9396926 = 10000 / d
d = 10000 / 0.9396926
d = 10641.777
