Find X and Y
I need help ASAP plz

Given:

In a right angled triangle ABC the perpendicular and the base measure 3 cm.

To find:

The hypotenuse and three trigonometric ratios.

Solution:

Pythagoras theorem:

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

Use Pythagoras theorem in triangle ABC.

[tex]Hypotenuse^2=(3)^2+(3)^2[/tex]

[tex]Hypotenuse^2=9+9[/tex]

[tex]Hypotenuse=\sqrt{18}[/tex]

[tex]Hypotenuse=3\sqrt{2}[/tex]

The three trigonometric ratios are

[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin \theta=\dfrac{3}{3\sqrt{2}}[/tex]

[tex]\sin \theta=\dfrac{1}{\sqrt{2}}[/tex]

Similarly,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos \theta=\dfrac{3}{3\sqrt{2}}[/tex]

[tex]\cos \theta=\dfrac{1}{\sqrt{2}}[/tex]

And,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\tan \theta=\dfrac{3}{3}[/tex]

[tex]\tan \theta=1[/tex]

Therefore, the hypotenuse is [tex]3\sqrt{2}[/tex] cm and three trigonometric ratios are [tex]\sin \theta=\dfrac{1}{\sqrt{2}}, \cos \theta=\dfrac{1}{\sqrt{2}}, \tan \theta=1[/tex].

Answer:

I think it’s 80

Step-by-step explanation:

Because it’s the same side just a different angle if it makes sense

Answer:

If the rope is 20 ft long, then the maximum area the cow can graze is:

[tex]\pi \\[/tex]r^2 square feet.

[tex]\pi[/tex] is approximately 3.14, so that means we have: 3.14(20^2) = 1256 ft squared.

Thus, the maximum area that the cow can graze is 1256 ft squared.

Let me know if this helps!

The cow's maximum grazing area is 1256 ft squared. The grazing area is found as the area of the circle.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.

If the rope is 20 feet long, the cow can graze the following area:

A=πr²

A=3.14(20)²

A=1256 ft squared.

As a result, the cow's maximum grazing area is 1256 ft squared.

Answer:

aₙ = 2*n*n - n -1

Step-by-step explanation:

a₁ = 0

a₂ = 5 = 2*2*2 -2-1 = 8-3 = 5

a₃ = 2*3*3 -3-1 = 18-4 =14

a₄ = 2*4*4 - 4-1 = 32-5 =27

Step-by-step explanation:

We need to isolate X!

y = mx + b

minus b

y-b=mx

divide by m

(y-b)/m = x

Answer:

BD = 32.5

Step-by-step explanation:

Since this is a square, the length of all the sides are equal. So line AB = BC = CD = DA = 23

Additionally, all the interior angles are the same (90°)

To find the length of BD, you can cut the square in half diagonally to form two right angled triangles, ABD and BCD.

For either one, BD is the hypotenuse of the right angled triangle so we can use Pythagoras' theorem to solve for the that (since we also know the legnth of the sides)

a = 23

b = 23

c = BD, which we have to find

[tex]a^{2} +b^{2} =c^{2} \\23^{2} +23^{2} =c^{2} \\\sqrt{23^{2} +23^{2} } = c\\\sqrt{529+529} =c\\\sqrt{1058} = c\\32.5 = c[/tex]

therefore the length of BD is 32.5

Answer:

1. 12.6  2. 21.4

Step-by-step explanation:

1. c=2piR, so if the radius is 2, then 2 times 2 then times 3.14= 12.6(rounding to the nearest tenth)

2.i already explained the formula, so it should be 3.4*2 then times 3.14= 21.4

the probability of getting one is 1/6, and 2 is the same, 1/6. the probability of getting a number higher than 4 is 1/3. 1/6 * 1/6 * 1/3 = 1/108

Answer:

Around 35%

Step-by-step explanation:

122/350 = 0.35

Answer:

32%

Step-by-step explanation:

We are told out of 350 times, he stuck out 122 times. As a fraction, we can say he struck out 122/350 times.

As a fraction, we can easily convert this to a decimal by dividing the numerator (top number) by the denominator (bottom number).

So, 122/350 = 0.32.

Now, we can easily convert this to a percentage by multiplying by 100.

0.32 x 100 = 32%

Answer: $64.20

Step-by-step explanation:

Cost of shoe = $60

Sales tax rate = 7%

Sale tax = 7% × $60 = 7/100 × 60 = $4.20

The total price paid by Mary

= Cost of shoe + Sales tax

= $60 + $4.20

= $64.20
