Answer:

Angle A = 65 degrees, Angle B = 78 degrees

Step-by-step explanation:

Since a triangle always has its vertices add up to 180 degrees to be a triangle, we can setup an equation on how to solve it. Adding all the vertices together into a formula to equal 180 degrees gives you 5x-5 = 180. Solving this equation will grant you an answer of x = 37 degrees, and taking this value and plugging it in for each requested angle is how to find the exact degree value. Angle A will just be 2(37) - 9, which ends up to be 65 degrees. Angle B is just 2(37) + 4, which becomes 78 degrees. (You can check the answer by taking all values and adding them together to equal 180. 78 + 65 + 37 = 180.) Hope that helps!

Answer: ∠A = 65° ∠B = 78°

The sum of all interior angles = 180°. So, set 180 equal to the angles you were given (in this case, 2x-9, 2x+4, and x), and solve for x.

180 = (2x-9) + (2x+4) + x (combine the like terms)

180 = 5x - 5 (isolate 5x by moving -5 to the other side)

5x = 180 + 5

5x = 185 (divide both sides by 5 to isolate for x)

x = 37°

Then, sub in the value of x (in this case, 37°) into ∠A and ∠B.

∠A = (2x-9) = 2(37)-9 = 65°

∠B = (2x+4) = 2(37)+4 = 78°

∴ ∠A = 65° and ∠B = 78°.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

Given;

Gianna walked 12 miles in 6 hours

6hours= 12 miles

1hour= 12/6miles

1hour= 2miles

Therefore, the rate of gianna by unitary will be 2mph

Which of the following correctly solves this equation? ( − 6 ) 2 − ( 6 ) ( 6 ) = 36 ( − 6 ) ( − 2 ) = 12 ( − 6 ) ( − 6 ) = 36 ( − 6 ) ( − 6 ) = − 36

Answers

The correct solution are:  ( − 6 ) ( − 2 ) = 12 and  ( − 6 ) ( − 6 ) = 36 .

Addition Sign Rules

Here it is important to remember the rules for the  addition of integers numbers:

+  +   Add  Final result (+) - Final result (+)  

-   -   Add  Final result (-) - Final result (-)  

+  -   Subtract - Final result (the sign of the integer having a greater value)

-   +  Subtract - Final result (the sign of the integer having a greater value)

Multiplication Sign Rules

The rules for multiplication of numbers are:

  +  +  or -   -

The result presents a positive sign (+) because the signs are the same.

  +  - or   -   +

The result presents a negative sign (-) because the signs are different.

For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.

Option1

        ( − 6 ) 2 − ( 6 ) ( 6 ) = 36

        -12 -(36) = -12 -36 = -48 -> It is not the solution given in the exercise because  -48 ≠ 36.

Option2

        ( − 6 ) ( − 2 ) =12

                12=12 -> It is the solution given in the exercise because  12=12.

Option3

      ( − 6 ) ( − 6 ) = 36

               36=36-> It is the solution given in the exercise because  36=36.

Option 4

       ( − 6 ) ( − 6 ) = − 36

            36≠ -36 -> It is not the solution given in the exercise because  36 ≠ -36.

Suppose you have $75 in your savings account and you save an additional $5 each week. Your friend has $30 in his savings account and saves an additional $10
per week. In how many weeks will you have the same amount of money?

Answers

Answer:

9 weeks

Step-by-step explanation:

5x+75=10x+30

-5x        -5x

75=5x+30

-30      -30

45=5x

÷5    ÷5

9=x

x=9

it will take 9 weeks for you and your friend to have the same amount of money in your savings accounts.

To determine the number of weeks it takes for both you and your friend to have the same amount of money in your savings accounts, we need to set up an equation.

Let's denote the number of weeks as 'x'. For you, the amount of money in your savings account after 'x' weeks can be calculated as follows:

Amount of money in your account = $75 + $5x

For your friend, the amount of money in his savings account after 'x' weeks can be calculated as:

Amount of money in your friend's account = $30 + $10x

To find the number of weeks where you both have the same amount of money, we set up the equation:

$75 + $5x = $30 + $10x

Simplifying the equation:

$5x - $10x = $30 - $75

-$5x = -$45

Dividing both sides of the equation by -5 gives us:

x = 9

Therefore, it will take 9 weeks for you and your friend to have the same amount of money in your savings accounts.

Answers

Answer/Step-by-step explanation:

1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°

2. m<ECF = m<BCD (corresponding angles)

m<ECF = 38° (substitution)

3. m<DCF + m<ECF = 180° (linear pair)

m<DCF + 38° = 180° (substitution)

m<DCF = 180° - 38° (Subtraction property of equality)

m<DCF = 142°

The measure of the following angles are as follows;

∠BCD = 38°

∠ECF = 38°

∠DCF = 142°

Angles form when a transversal cut parallel lines

When a transversal line cut across parallel lines, the angles form include corresponding angles, alternate angles etc.

Therefore,

∠BCD = 38 degrees(alternate angles)

∠ECF = 38 degrees(corresponding angles)

∠DCF = 180 - 38 = 142 degrees(angles on a straight line)
