Answer:

$620

Step-by-step explanation:

Let the price of refridgerator be "r"

price of washer be "w"

and

price of dryer be "d"

Total 1800, that means, we can write:

r + w + d = 1800

Also, refrigerator cost 250 more than washer, so we can write:

r = w + 250

The dryer is HALF (0.5) of washer, so we can write:

d = 0.5w

Now, we replace equation1 with equation 2 & 3, so get an equation in "w" and solve for w:

r + w + d = 1800

w + 250 + w + 0.5w = 1800

2.5w + 250 = 1800

2.5w = 1800 - 250

2.5w = 1550

w = 1550/2.5

w = 620

Thus, the washer costed $620

<h3>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.
