Whats The Measure Of Angle X?

Answers

Answer 1

Answer:

x = 84°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

129° is an exterior angle of the triangle, thus

x + 45° = 129° ( subtract 45° from both sides )

x = 84°

The 2 triangles formed by the tree/ shadow and Jordan/ shadow are similar and ratio of corresponding sides are equal, that is

let h be the height of the tree, then

[tex]\frac{h}{7}[/tex] = [tex]\frac{50}{10}[/tex] = 5 ( multiply both sides by 7 )

h = 35

The height of the tree is 35 ft

If the width of a rectangle is 9 ft less then twice it’s length and the perimeter is 30 feet, what are the dimensions of the rectangle?

Answers

9 times 30, and the other number would be 18 :))

The dimension of the rectangle is,

The length of the rectangle is 7 feet.

And the width of the rectangle is 8 feet.

Given that,

If the width of a rectangle is 9 ft less than twice its length and the perimeter is 30 feet,

We have to determine,

What are the dimensions of the rectangle?

According to the question,

Let, the width of the rectangle is W,

And the length of a rectangle is L = 2W - 9,

The perimeter of the rectangle is = 2(L+W)

Where perimeter is 30 feet,

Therefore,

[tex]30 = 2(2W-9+W)\\\\30 = 2(3W-9)\\\\30 = 6W-18\\\\30 + 18 = 12W\\\\48 = 6W\\\\W = \dfrac{48}{6}\\\\W = 8 \ feet[/tex]

And the length of a rectangle is,

[tex]L = 2W - 9, \\\\L= 2(8) - 9\\\\L = 16-9 \\\\L =7 \ feet.[/tex]

Hence, The dimension of the rectangle is, the length of the rectangle is 7 feet, and the width of the rectangle is 8 feet.

Mary borrowed $840 from her friend to help pay for a trip. She paid him $40 every
week until the debt was paid.
How many weeks did it take Mary to pay her debt?
A. 40
B. 35
C. 32
D. 21

Answers

Answer:

d.21

Step-by-step explanation:

840/40=21

Answer:

21 Weeks

Step-by-step explanation:

$840 ÷ 4 weeks = 21

You can also reverse work this by multiplying $40 by the other choices!

$40 x 40 = $1600

$40 x 35 = $1400

$40 x 32 = $1280

$40 x 21 = $840

As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

Step-by-step explanation:

Insert the 5 into the place of the X.

Then solve:

-4 - 6(5)

= -4 - 30

= -34

The answer is -34, the equation is asking what the output would be if x were to equal 5. -6 multiplied by 5 equals -30, then -4 and -30 combined is -34

(2x + 127)° = 107°

2x + 127 = 107

2x = 107 - 127

2x = - 20

Step-by-step explanation:

first, you want to graph your points on a graph. A really good online graphing calculator i like is called desmos.

next, slope is rise over run. count how many units up or down from leftmost point to the other. in this case it is -8.

third, find the run part of the slope by counting units right or left from the leftmost point to the other. in this case it is 4.

last, but the two numbers together in a fraction and simplify. rise over run.

-8/4 which simplifies to -2/1 which is the same thing as -2

4+3(x+2)=12
Plz answer ​

Answers

Answer: x = 2/3

Step-by-step explanation:

Let's solve your equation step-by-step.

4+3(x+2)=12

Step 1: Simplify both sides of the equation.

4+3(x+2)=12

4+(3)(x)+(3)(2)=12(Distribute)

4+3x+6=12

(3x)+(4+6)=12(Combine Like Terms)

3x+10=12

3x+10=12

Step 2: Subtract 10 from both sides.

3x+10−10=12−10

3x=2

Step 3: Divide both sides by 3.

3x/3 = 2/3

ANSWER: x = 2/3
