Someone plzzz tell me this answer i am really stuck on this

Answer:

sin(A) = opp / hyp

=a/hyp. =9/15

cos(A) = adj/hyp

=b/hyp. =12/15

Tan(A) = sin(A) / cos(A)

= 9/15 / 12/15

=9/12. (you can further simplify it)

same for the B angle,

sin(B) = b/15

=12/15

cos(B) = a/15

=9/15

tan(B) = sin(B) / cos(B)

= 12/15 / 9/15

=12/9

Answer:

180 different four-course meals

Step-by-step explanation:

So you have one out of 3 salads, one out of 3 appetizers, one out of 4 entrees, and one out of 5 deserts. To find the number of meals that are possible, multiply 3 by 3 by 4 by 5

3 * 3 = 9

9 * 4 = 36

36 * 5 = 180

Answer:

∠x = 39.6°

Step-by-step explanation:

tan x = 19/23 = 0.8261

x = 39.6°

Answer:

x=4

Step-by-step explanation:

if AB = 2x-5 and AC = 3x-9 and AB=AC then:

2x-5 = 3x-9

-x-5=-9

-x=-4

x=4

Answer:

{y = 15/8 - (9 x)/8, y = -(7 x)/8 - 2}

{9 x + 8 y = 15, 7 x + 8 (y + 2) = 0}

Step-by-step explanation:

Answer:

b = 2

Step-by-step explanation:

For the graph to pass through the point, we have it that the coordinates of the point will work in the equation of the line

Hence, by substituting the x value, we can get the y value and by substituting the y value, we can get the x value

where f(x) is same as y in this case

Thus, we have it that;

3 = -(-1) + b

3 = 1 + b

b = 3-1

b = 2

Answer:

76, 70, 64, 58, 52

Step-by-step explanation:

76 - 6 = 70

70 - 6 = 64

64 - 6 = 58

58 - 6 = 52

Answer:

76,70,64,58,52

Step-by-step explanation:

Observation all the terms in the pattern are even.

Answer:

12 units squared

Step-by-step explanation:

You need to find the area of each individual shape, and then add them together. The area of the square is 4 units squared. The triangle on the left is two units squared (base times height, divided by two,) and the area of the triangle on the left is 6. Add them all together, and you get 12 units squared.

Answer:

24

area is round the outside times them together and you will get the inside

brainly won't let me type my answer out so i'll just put it in the comments, sorry if it's inconvenient.

Answer:

i think the answer to this question is 2.461

Step-by-step explanation:

For a semicircle, the total perimeter includes half of the circumference + the diameter.

The half circumference is given by 2 pi r / 2

So the perimeter of 19.02 = 2pi r/ 2 + 2r

Answer:

This equation has two solutions.

1 solution is: x - 1

Solution #2 is : x - 7

Step-by-step explanation:

1. Move the constant to the left. We end up with x^2 - 8x +7 = 0

2. Rewrite the expression: x^2 - x - 7x + 7 = 0

3. Factor the expressions: x * (x-1) -7(x-1) = 0

4. Separate into possible cases : (x-1) * (x-7) = 0

5. Solve the equation(s): x-1 = 0

                                         x-7 = 0

6. Possible solutions are as follows: x-1 OR x-7

Answer:

$40

Step-by-step explanation:

Find the original price by dividing 28 by 0.7

28/0.7

= 40

So, the original price was $40

Answer:

125

Step-by-step explanation:

note that

625 = [tex]5^{4}[/tex]

Using the rule of exponents

[tex](a^{m}) ^{n}[/tex] ⇔ [tex]a^{mn}[/tex]

Then

[tex](5^{4}) ^{\frac{3}{4} }[/tex]

= 5³

= 125

Answer:

what this isnt a question plz fix this then I'll anwser

Answer:

Are you asking for the definition? If so

Step-by-step explanation:

A whole number is part of a fraction. A fraction has to parts EX: 5/4

5 would be the numerator and 4 is denominator

Dividing a fraction and another fraction would be just like multiplying fractions. Reverse of the other

Hope this helped! Maybe be more specific next time? Anyways hope you have a wonderful day! :)) <33

Answer:

c=-6

Step-by-step explanation:

I used a calculator and paper and a pencil d---------b yeah :D yr welcome

Ok, so you would want to simplify both sides of the equation

(-1/3)(-12) + (1/3)(-12c)=-20 (here you distribute)

4+4c=-20

Then, subtract 4 from both sides

4c+4-4=-20-4

4c=-24

Then divide both sides by 4

4c/4=-24/4

c=-6

Answer:

Step-by-step explanation:

The measure of sides of ΔPQR are PQ=13 units, QR=5 units and RP=2 units.

Given that, triangle PQR whose vertices are located at P(-5, 2), Q(7,-3), R(7, 2).

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Using distance formula,

PQ =√[(7+5)²+(-3-2)²]

= √169

= 13 units

QR =√[(7-7)²+(2+3)²]

= √25

= 5 units

RP =√[(-5+7)²+(2-2)²]

= √4

= 2 units

Therefore, the measure of sides of ΔPQR are PQ=13 units, QR=5 units and RP=2 units.
