What is the slope of (1,2) and (3,2)

sweet [91]

Answer:

Step-by-step explanation:

(1,2) ; (3,2)

slope = y₂ - y₁ / x₂ - x₁

= ( 2-2 )/( 3 - 1) = 0

So, the line is parallel to x-axis and its slope is 0

Note that while the figure is made up of rectangle and parallelogram, then the area of this figure

$A_{figure}=A_{rectangle}+A_{parallelogram}.$

1. The area of rectangle is

$A_{rectangle\ ABCF}=AB\cdot BC.$

The vertices of rectangle are points A(-2,-2), B(0,-6), C(8,-2) and F(6,2). Then

$AB=\sqrt{(-2-0)^2+(-2+6)^2}=\sqrt{4+16}=\sqrt{20}=2\sqrt{5},\\ \\BC=\sqrt{(8-0)^2+(-2+6)^2}=\sqrt{64+16}=\sqrt{80}=4\sqrt{5}.$

Therefore,

$A_{rectangle\ ABCF}=2\sqrt{5}\cdot 4\sqrt{5}=8\cdot 5=40\ un.^2$

2. The area of parallelogram can be calculated using formula

$A_{parallelogram\ FCDE}=\text{base}\cdot \text{height}.$

The base of parallelogram is segment CD with length

$CD=\sqrt{(8-8)^2+(3+2)^2}=\sqrt{25}=5$

and the height has length 2 un. Then

$A_{parallelogram\ FCDE}=5\cdot 2=10\ un^2.$

3. Now

$A_{figure}=40+10=50\ un.^2$

How to get these variables?

garri49 [273]

Given:

Right triangle with one angle 45°

To find:

The value of q and r.

Solution:

Opposite to θ = 16

Adjacent to θ = r

Hypotenuse = q

Using trigonometric ratio formula:

$$\tan \theta =\frac{\text{Opposite side to } \theta}{\text{Adjacent to } \theta}$

$$\tan 45^\circ =\frac{16}{r}$

The value of tan 45° = 1

$$1 =\frac{16}{r}$

Do cross multiplication, we get

r = 16

Using trigonometric ratio formula:

$$\sin \theta =\frac{\text{Opposite side to } \theta}{\text{Hypotenuse}}$

$$\sin 45^\circ =\frac{16}{q}$

The value of sin 45° = $\frac{1}{\sqrt{2} }$ .

$$\frac{1}{\sqrt{2} } =\frac{16}{q}$

Do cross multiplication, we get

$q=16\sqrt{2}$

The value of r is 16 and the value of q is $16 \sqrt{2}$ .
