70.1 ft² of fabric is needed by Lacy to make the sail boat.

<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.

Which two values of x are roots of 4x^2-6x+1
aleksandr82 [10.1K]

x= 3+√5/4,3-√5/4

Step-by-step explanation:

1.In general, given ax^2+bx+c=0, there exists two solutions where:

x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a

2.In this case, a=4, b=-6 and c=1.

x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4

3.Simplify.

x=6+2√5/8, 6-√5/8

4.Simplify solutions.

x=3+√5/4, 3-√5/4

How far up does the ladder reach on the building?
pychu [463]

Step-by-step explanation:

The question missing attachment (incomplete)

But the question said how far up does the ladder reach on the building?

See the attachment

Let the tita be 60° and the height of the building be 50 meters

Now

Opposite/hypotenuse = sin(tita)

50/x = sin60°

Cross multiply to find x

x = 50/sin(60°)

x= 50/0.8660

x=57.7 meters
