Trigonometric functions are the ratio of the different sides of a right-angled triangle. We can say that the coordinates of the point are (-77, 36).

Trigonometric functions are the ratio of the different sides of a right-angled triangle.

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

Given to us

[tex]Sin(\theta) = \dfrac{-77}{85}[/tex]

[tex]Cos(\theta) = \dfrac{36}{85}[/tex]

[tex]Tan(\theta) = \dfrac{-77}{36}[/tex]

As we know that the Tangent(Tan) is the ratio of perpendicular and base. therefore, we can write the function as,

[tex]\rm Tan(\theta) = \dfrac{Perpendicular}{Base} = \dfrac{-77}{36}[/tex]

therefore, the length of the perpendicular is 77, while the length of the base is 36.

As given to us that the value of sin is negative, therefore, the perpendicular will be on the negative side of the y-axis. While the value of cos is positive, therefore, the base will be on the positive side of the x-axis.

Thus, we can say that the coordinates of the point are (-77, 36).

Answer:

  x = 4

Step-by-step explanation:

In this geometry, all of the right triangles are similar. That means the ratio of short side to long side is the same for all of the right triangles:

  x/10 = 10/25

  x = 100/25 = 4 . . . . . multiply by 10

_____

Additional comment

You may notice that the two segments of the hypotenuse, x and 25, have a product that is the square of the altitude. Another way to say this is that the altitude is the geometric mean of the segments x and 25.

There are two other geometric mean relations in this geometry:

  the short side at the right is the geometric mean of x and (x+25).

  the long side at the bottom is the geometric mean of 25 and (25+x).

That is, the segments that intersect the hypotenuse are the geometric mean of the two segments of the hypotenuse that they meet.

  geometric mean of A and B is √(AB)

Answer:

58.57 approximately 58.6

Step-by-step explanation:

we've been given the value for line MN as 67.2m and also line AN as 32m so we look for line MA by saying 67.2 minus 32m to give 35.2m

considering the big triangle we have line MN and we have line MP but we don't have line NP to get line NP we use pythagoras theorem

hypotenuse Square = opposite Square + adjacent Square

81.9*2= 67.2*2 + x*2

therefore x is 46.8m

note that line NP is equal to line AB therefore line AB is also 46.8m

so we now look at the smaller triangle to find x

that's also pythagoras theorem

hypotenuse Square = opposite Square + adjacent Square

x^2 = 38.5^2 + 46.8^2

therefore our value for x is 58.6

Answer:

416

Step-by-step explanation:

Well I know 8 x 100=800 so I did 8 x 400=3,200

Then I added 8 x 10=80 which is 3,280

and from there I did 8 x 6=48

And then what's 3,280+48=3,328 because 3,280+40=3,320 and then add 8=3,328

Hope it helps

Answer:

If we break apart 3,328 and first divide 3,000 by 8 we get 375, and then divide 328 by 8 we get 41, this helps us understand that if we divided 3,328 by 8 we would get 416

Answer:

Hello I'll help you :))!

So there are 21 numbers from 60 to 80 both terms inclusive.

We ignore all even numbers in this range as even numbers can not be prime.

The odd numbers are 61,63,65,67,69,71.73,75,77,79.

So remaining numbers are prime. They are 61,67,71,73,79.

So there are 5 prime numbers in this range.

Answer:

base = 32 cm , height = 40 cm

Step-by-step explanation:

ratio of base : height = 4 : 5 = 4x : 5x ( x is a multiplier )

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height ) , then

A = [tex]\frac{1}{2}[/tex] × 4x × 5x = 2x × 5x = 10x²

given A = 640 , then

10x² = 640 ( divide both sides by 10 )

x² = 64 ( take square root of both sides )

x = [tex]\sqrt{64}[/tex] = 8

Then

base = 4x = 4 × 8 = 32 cm

height = 5x = 5 × 8 = 40 cm

I'm kinda guessing from the question u gave cuz it doesn't really have a lot of information

Answer:

x=20

Step-by-step explanation:

These these angles are adjacent

because they share a vertex and side. They also form a linear pair meaning they add up to 180 degrees...

x+20+7x=180

Combine like terms

8x+20=180

Subtract 20 from both sides

8x=160

Divide both sides by 8

x=20

Answer: 12

Step-by-step explanation:

Following PEMDAS, I’ll solve the multiplication first and then add or subtract the values from left to right.

1-2+5-2+5x2

1-2+5-2+10

-1+5-2+10

4-2+10

2+10

12

Answer:

12

Step-by-step explanation:

You need to use the order of operations, PEMDAS. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

First, multiplication on 5x2 so now it is 1-2+5-2+10.

Next, is addition and subtraction. When it says left to right you are starting with the part of the equation closest to the left, so 1-2=-1. Then add five to get 4. Subtract 2 to get 2. Finally, add 10 to get 12.

Hope you get an A! <3

Answer:

The numbers are 4 and 6

Step-by-step explanation:

Let:

we know that

[tex]x^{2} =(x+2)+10[/tex]

solve for x

[tex]x^{2} -x-12=0[/tex]

We can use the quadratic formula for quadratics in the form [tex]ax^{2} +bx+c=0[/tex]

[tex]x= \frac{-b(+/-)\sqrt{b^{2} -4ac}}{2a}[/tex]

to give us an answer of 4 and -3

Since the question states positive and even we use 4 and that gives us 6 as the other answer
4 and 6

Answer:

4 and 6

Step-by-step explanation:

x = smaller integer

x+2 = larger integer

x² = 10 + (x + 2)

x² = x + 12

x² - x - 12 = 0

factors are:

(x-4)(x+3) = 0

x-4=0;  x = 4

x+3=0;  x = -3

Since the question states the numbers are even and positive we use only the 4 and the next consecutive even integer is 6

Answer:

an = a+(n-1) d

this is the rule

Answer:

nth term = 21 - 3n

Step-by-step explanation:

18,15,12,9....

This is an arithmetic sequence.

a= first term = 18

Common difference = d = second term - first term

d = 15 - 18

d = -3

nth term = a + (n-1)d

             = 18 + (n-1)*(-3)

              = 18 + n*(-3) - 1*(-3)

              = 18 - 3n + 3

               = 21 - 3n

Answer:

3

Step-by-step explanation:

[tex]x=\sqrt{2x+3}[/tex]

square both sides:   [tex]x^2=2x+3[/tex]

subtract [tex]2x + 3[/tex] from both sides:  [tex]x^2-2x-3=0[/tex]

factorize:  [tex](x-3)(x+1)[/tex]

Therefore, [tex]x=3 \ and \ -1[/tex]

Substitute found values of [tex]x[/tex] back into original equation:

[tex]3=\sqrt{2\times3+3}=3 \ \ \checkmark[/tex]

[tex]-1=\sqrt{2\times-1+3}=1[/tex]  incorrect!

So answer is [tex]x = 3[/tex] only
