Avessel sails 32 miles s 45 e. how far south has it sailed?

If there is 45 angle from the south to the east α= 45° then the distance of d=32miles is

the diagonal of the square and your question how far south has it sailed is the side of the square let's call it x.

The relation is

d = x √2 => x= d/√2 = 32/1.41 ≈ 22.69 ≈ 22.7 miles

The correct answer is 22.7 miles

Good luck!!

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
