Area of trapezoid = a + b/2 * h
a = 20, b = 9, h = 21/-16
20+9/2 * (21-16) = 29/2 * 5 = 72.5
The area of the trapezoid = 72.5 in^2

Area of the rectangle = l * w
l = 16, w = 20
16 * 20 = 320
The area of the rectangle: 320 in^2

With reference to the figure, sin X equals?<br> 1.) 0.250<br> 2.)0.447<br> 3.)0.894<br> 4.)1

Flura [38]

Answer:

3.) 0.894

Step-by-step explanation:

✔️First, find BD using Pythagorean Theorem:

BD² = BC² - DC²

BC = 17.89

DC = 16

Plug in the values

BD² = 17.89² - 16²

BD² = 64.0521

BD = √64.0521

BD = 8.0 (nearest tenth)

✔️Next, find AD using the right triangle altitude theorem:

BD = √(AD*DC)

Plug in the values into the equation

8 = √(AD*16)

Square both sides

8² = AD*16

64 = AD*16

Divide both sides by 16

4 = AD

AD = 4

✔️Find AB using Pythagorean Theorem:

AB = √(BD² + AD²)

AB = √(8² + 4²)

AB = √(64 + 16)

AB = √(80)

AB = 8.9 (nearest tenth)

✔️Find sin x using trigonometric ratio formula:

Reference angle = x

Opposite side = BD = 8

Hypotenuse = AB = 8.944

Thus:

$sin(x) = \frac{opp}{hyp} = \frac{8}{8.944} = 0.894$ (nearest thousandth)

Which information can always be read directly from an equation written in point-slope form?

Mariulka [41]

Answer:

The location of a point on the line

Step-by-step explanation:

Generally, we can write an equation in the point slope form as follows;

y-y1 = m(x-x1)

Where m is the slope of the line

So looking at the option, we can easily see that the information we can read directly from the point-slope form is the location of a point on the line.

We can easily tell the value of (x1,y1) which easily gives out the location of that point on the line

72÷x=3.6÷0.015 what is the answer?

lapo4ka [179]

Answer:

The answer you are looking for is x = 3/10

Step-by-step explanation:

D( x )

x = 0

x in (-oo:0) U (0:+oo)

72/x = 3.6/0.015 // - 3.6/0.015

72/x-(3.6/0.015) = 0

72/x-240 = 0

72*x^-1 = 240 // : 72

x^-1 = 10/3

-1 < 0

1/(x^1) = 10/3 // * x^1

1 = 10/3*x^1 // : 10/3

3/10 = x^1

x = 3/10
