In triangle ABC, If cos (A) = 12/13 and sin (A) = 5/13, what is tan(A)?

Answer:

7.5

Step-by-step explanation:

you have to double it to get 6 then half of 3 is 1.5 so 6 plus 1.5 is 7.5

Answer:

7.5 miles

Step-by-step explanation:

1 inch = 3 miles

1 inch = 3 miles

1/2 inch = 1.5 miles

3+3+1.5 = 7.5 miles

Answer: AB = 150 degrees

Step-by-step explanation: 90 + 60 = 150

Step-by-step explanation:

Answer:

(A)1/3

Step-by-step explanation:

probability of getting a 2 = 1/6

probability of getting a 6 = 1/6

so the probability of getting a 2 or a 6

=(probability of getting a 2+probability of getting a 6)

=(1/6+1/6)

=2*(1/6)

=1/3

16) 95.03in²

17) 52.81ft²

18) 153.94mi²

19) 162.86mi²

20)452.39ft²

Step-by-step explanation:

Step-by-step explanation:

To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.

Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.

The radius is half of the diameter. So for number 8, the answer would be 2.

hope this helps and that it wasn't to confusing  :)

This is your answer ☺️

Answer:

x = 3, y = - 1

Step-by-step explanation:

Given the 2 equations

6x + 4y = 14 → (1)

- 5x + 12y = - 27 → (2)

Multiplying (1) by - 3 and adding to (2) will eliminate the y- term

- 18x - 12y = - 42 → (3)

Add (2) and (3) term by term to eliminate y

- 23x + 0 = - 69

- 23x = - 69 ( divide both sides by - 23 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

6(3) + 4y = 14

18 + 4y = 14 ( subtract 18 from both sides )

4y = - 4 ( divide both sides by 4 )

y = - 1

solution is (3, - 1 )

Answer:

This is known as null effect

Step-by-step explanation:

A null effect is the outcome of an experiment that does not give the effect or result expected. Although an experiment with a null effect has a result, however the result of the experiment does not support the hypothesis

An example of a null result that remains importantly useful is the Michelson-Morley experiment from that partly made possible the formulation of special relativity theory

Answer:

AB, BC, AC

Step-by-step explanation:

Hi there,

In order to solve this problem, we should know that the longest side of the triangle is always opposite of the largest angle in a triangle. The first step is to find the angle measures. We are given the measures of ∠A and ∠C.

To find m∠B, just subtract the sum of the other angles and subtract the value from 180.

m∠A + m∠C + m∠B = 180°

65° + 40° + m∠B = 180°

105° + m∠B = 180°

m∠B = 75°

Now that we know all of the angle measures, we can identify the the lengths of the sides from least to greatest by looking at the angle value. The greater the angle measure, the longer the opposite side would be.

m∠A = 65° ⇒ opposite of side BC = medium side

m∠B = 75° ⇒ opposite of side AC = longest side

m∠C = 40° ⇒ opposite of side AB = shortest side

Hope this explanation helps. Cheers.

Answer:

Step-by-step explanation:

Answer:

Umm what's the question

Answer:

a) 24 degrees

b) 50 degrees

Step-by-step explanation:

part a : use sine-1

sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]

sine-1 = [tex]\frac{17}{42}[/tex]

sine-1 = 0.405

missing angle = 23.89

round to the nearest degree = 23.89 = 24

part b : use cosine-1

cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]

cos-1 = [tex]\frac{16}{25}[/tex]

cos-1 = 0.64

missing angle = 50.208

round to the nearest degree = 50.208 = 50

Answer:

4(11y +22)

Step-by-step explanation:

5(9y+19.8) =45y+99

9(5y+11)=45y+99

2(22.5y+49.5)=45y+99

4(11y+22)=44y+88

you must expand the numbers to get the total

for example you multiply 5×9y and 5×19.8 in a

Answer:7(3+5)= 21+35

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

Given

4(x - 2) = 12 ( divide both sides by 4 )

x - 2 = 3 ( add 2 to both sides )

x = 5

Answer:

The answer is (y - 1)^3 = (y - 1) (y^2 + y + 1)

Step-by-step explanation:

[tex](y - 1)^{3} = (y - 1)( {y}^{2} + y \: \: 1 + {1}^{2} ) \\ \\(y - {1)}^{3} = (y - 1)( {y}^{2} + y + 1)[/tex]

Answer:

x= 128*

Step-by-step explanation:

180*-52*=128*

Answer:

x = 128

Step-by-step explanation:

well we know that for a polygon, the interior angles always add up to 360.

One angle is 52, and since the other two have squares it means that they are a perfect 90 degree angle. add those up to get 232, and then subtract 232 from 180 to get 128

Answer:

h=1ft

Step-by-step explanation:

The volume of a cone is:

v=πr^h/3

plug in the values (I am assuming not 1/18π but 1/18×π):

1/18π=  π1/3^2h/3

Get rid of the radius:

1/3^2=1/9

Continue:

π/18= πh/3*1/9= πh/18

Remove the denominators:

π=πh

Divide both sides by π :

h=1

Answer:

x = 25

Step-by-step explanation:

2x + 70 = 120      {Subtract 70 from both sides}

        2x = 120 -70

        2x = 50      {divide both sides by 2}

          x = 50/2

x = 25
