solve this: a triangle has an engle of 38. this is a scalene right triangle. one of the sides are 8 in length. what are the other angles?

Answers

Answer 1

Answer:

 52°, 90°

Step-by-step explanation:

The two acute angles in a right triangle are complementary, because the third angle is 90°. For acute angles A and B, we must have ...

  90° + A + B = 180°

  A + B = 90° . . . . . subtract 90°; definition of complementary angles

  B = 90° - A

For angle A = 38°, this tells us ...

  B = 90° -38° = 52°

The other two angles in the triangle are 90° and 52°.

Answer:

[tex]B = \frac{3}{2} * 21,356[/tex]

Step-by-step explanation:

Given

Represent Jimmy with J and Bob with B

[tex]J = 21,356[/tex]

[tex]B = 1\frac{1}{2} * J[/tex]

Required

Determine the expression for B

[tex]B = 1\frac{1}{2} * J[/tex]

Substitute 21,356 for J

[tex]B = 1\frac{1}{2} * 21,356[/tex]

Convert Mixed fraction to improper

[tex]B = \frac{3}{2} * 21,356[/tex]

The above is an expression for B

Solving further, we have

[tex]B = \frac{3 * 21,356}{2}[/tex]

[tex]B = \frac{64068}{2}[/tex]

[tex]B = 32034[/tex]

Answers

Answer:y=28

Step-by-step explanation:

all triangles add up to 180 and this triangle is an isosceles triangle so 34 should be equal to x-5 meaning that two of the angles are 34 degrees and you just need to subtract 34(2) from 180 which is  180-68 to give you 112. Then since this is the value of 4 times y, just divide 112 by four to isolate the variable and you get 28.

Solve the equation: 3x - x + 2 = 4(2x - 1) infinite solutions x = 1 x = -1 no solution

Answers

Answer:

[tex]x=1[/tex]

B

Step-by-step explanation:

So we have the equation:

[tex]3x-x+2=4(2x-1)[/tex]

Combine like terms on the left:

[tex]3x-x+2=4(2x-1)\\2x+2=4(2x-1)[/tex]

Distribute out the right:

[tex]2x+2=4(2x-1)\\2x+2=8x-4[/tex]

Subtract 2x from both sides. The left side cancels:

[tex](2x+2)-2x=(8x-4)-2x\\2=6x-4[/tex]

Add 4 to both sides. The right side cancels:

[tex]2+4=(6x-4)+4\\6=6x[/tex]

Divide each side by 6:

[tex](6)/6=(6x)/6\\x=1[/tex]

Therefore, the solution is: x=1.

X = 1

Porque:

3x - x + 2 = 4(2x - 1)

3x - x + 2 = 8x - 4

3x - x - 8x = - 4 - 2

- 6x = - 6

x = - 6/ -6

x = 1 ✔️

vertically translated 5 units


can someone help me find the equation

Answers

I think your talking about quadratics, so

They didn’t specify which way the parabola was translated, right or left, up or down?

Since there wasn’t specification of direction, I will use positive (to the right) and up (upwards)

a = 1/2
h = +5
k = +5

y = a(x-h)^2+k
y = 1/2 (x - 5)^2 + 5

Now if your writing it in standard form (above was vertex form) you’d just expand it

y = 1/2 (x-5)(x-5) + 5
y = 1/2 [(x^2) -5x -5x ] + 25 + 5
y = 1/2 x^2 - 5x + 30

A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept for seven days, while Susy paid ₹21 for the book she kept for five days. Find the fixed charge and the charge for each extra day.​

Answers

Answer:  fixed charge = 15,   extra day = 3

Step-by-step explanation:

Let x represent the charge for an extra day (after 3 days)

Let y represent the fixed charge (for first 3 days)

Equation 1:    7 days is 4 extra days   -->      4x + y = 27

Equation 2:   5 days is 2 extra days   -->     2x + y = 21

Multiply the second equation by -1 and add the two equations together:

                   4x + y = 27

                 -2x  - y = -21  

                  2x       =   6

                          x = 3

Input x = 3 into either equation to solve for y:

2x + y = 21

2(3) + y = 21

         y = 15

Marlon is bowling in a tournament and has the highest average after 5 games, with scores of 210, 225, 254, 231, and 280. In order to maintain this exact average, what must be Marlon’s score for his 6th game?

Answers

Answer:

240

Step-by-step explanation:

Right now, Marlon's average is (210 + 225 + 254 + 231 + 280) / 5 = 240. To maintain that average, the sum of Marlon's scores after 6 games must be 240 * 6. Currently, the sum of Marlon's scores is 240 * 5 so he must score a 240 * 6 - 240 * 5 = 240(6 - 5) = 240 * 1 = 240 for his last game.

Two people share $52.20 in the ratio 4:5. How much does each person receive?

Answers

ill take the 52.20 aint no splitting

Answer:

$23.20 and $29

Step-by-step explanation:

We can set up a simple equation to solve this problem.

4x + 5x = 52.2

9x = 52.2

x = 5.8

To find out how much each person received, we multiply 5.8 with the ratio numbers 4 and 5. That gives us $23.20 and $29, respectively.

The points S, T, U and V all lie on the same line segment, in that order, such that the
ratio of ST : TU: UV is equal to 6:2:3. If SV = 22, find TV.

Answers

Answer: TV = 10

==============================================

Explanation

Let x be some positive real number such that

ST = 6xTU = 2xUV = 3x

leading to the ratio

ST:TU:UV = 6x:2x:3x = 6:2:3

Note how I effectively started with 6:2:3 and multiplied all parts of the ratio by x to get 6x:2x:3x

-----------------

The parts of the ratio add up to the longest segment SV

ST+TU+UV = SV

6x+2x+3x = 22

11x = 22

x = 22/11

x = 2

Therefore,

ST = 6x = 6*2 = 12TU = 2x = 2*2 = 4UV = 3x = 3*2 = 6

Note how ST+TU+UV = 12+4+6 = 22, which is the length of SV. This helps confirm we have the correct x value.

-----------------

The last step is to find the length of TV

TV = TU+UV

TV = 4+6

TV = 10

Or you could do

ST + TV = SV

12+TV = 22

TV = 22-12

TV = 10

hi help me (2·4)²= this is other (6:2)²+

Answers

Answer:

(2·4)² = 64  /  (6*2)² = 144

Step-by-step explanation:

Follow PEMDAS :

Parenthesis first, so:

2 * 4

==> 8

Then Exponent:

8 ^2

==> 64

(2·4)² = 64

Do the same for (6:2)² :

Parenthesis first :

6 * 2

==> 12

Then Exponent:

12^2

==> 144

(6:2)² = 144

Answer:

1. 64 is the answer.2. 144 is the answer

Step-by-step explanation:

First, multiply the numbers inside the parenthesis. So

1. 2*4 = 8

2. 6*2 = 12

Next, Use the exponents

1. 8^2

2. 12^2

Finally, solve using exponents.

1. 8^2 = 64

2. 12^2 = 144

So 64 and 144 is the answer.
