The Image of the triangle is missing and so i have attached it.
Answer:
B: 12 cosec 65°
Step-by-step explanation:
From the diagram attached, we cans see the triangle is a right angle triangle with a given internal angle of 65° and side AB with a length of 12 ft.
Now, we can use trigonometric ratios to find the distance the box has to move from point A to point C which is basically the distance AC.
Now, the given side AB is opposite to the angle. While the required side AC is the hypotenuse.
Thus;
Opposite/hypotenuse = sin θ
Thus;
AB/AC = 12/AC = sin 65
Thus;
AC = 12/sin 65
From trigonometric relationships, we know that;
1/sin θ = Cosec θ
Thus;
AC = 12 cosec 65
