Trigonometric ratio</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let b represent the base of the triangle and h the height, hence:
sin(60) = h / 18
h = 15.6 feet
sin(30) = b / 18
b = 9 feet
The area of triangle = (1/2) * b * h = 0.5 * 9 * 15.6 = 70.1 ft²
70.1 ft² of fabric is needed by Lacy to make the sail boat.

Answer:
9 inches
Step-by-step explanation:
I assume you mean the volume of the box is 450.
In that case, to figure out for the volume we multiply 10 by 5. This gives us 50.
450/50=9
The height of the box is 9 inches
