Step 1: Define

We are given a right triangle. We can use Trig Rations to solve for the missing side

Step 2: Identify Variables

Adjacent leg = x

Hypotenuse = 16

Angle ∅ = 50°

Step 3: Solve for x

Answer:

linear, 264*2 = 528

Step-by-step explanation:

Answer:

Step-by-step explanation:

x and y are variables. That means they represent numbers that are unknown. When we solve for x or y, we are trying to find what number the variable represents.

Y is a number that equals both 5x-9 and 3x+7. If it is a number, it can only have one value, so we can say that 5x-9 and 3x+7 have the same value.

In other words, 5x-9 = 3x+7.

Another way of thinking about this step is substitution. y=3x+7, so in the equation y=5x-9, we can replace the y with 3x+7. It will give 3x+7 = 5x-9.

In either case, we have this new equation

5x-9 = 3x+7.

From here it's just simple algebra- subtract 3x from each side

2x -9 = 7

and add 9 to each side

2x = 16

and divide each side by 2.

x = 8.

All these steps work because if two things equal each other, when you do the same thing to both of them (such as add 9), the new values will still equal each other.

Now that we know that x = 8, we can take one of the original equations

y=5x-9

and put 8 in for x.

y=5*(8) -9.

If x represents the value 8, we can obviously switch out x for 8.

Now simplify

y=40 -9

y = 31

Now we know that x = 8 and y = 31.

Answer:

x=8 and y=31

Let's solve your system by substitution.

y=5x−9;y=3x+7

Step: Solve y=5x−9for y:

y=5x−9

Step: Substitute5x−9foryiny=3x+7:

y=3x+7

5x−9=3x+7

5x−9+−3x=3x+7+−3x (Add -3x to both sides)

2x−9=7

2x−9+9=7+9(Add 9 to both sides)

2x=16

2x/2=16/2 (Divide both sides by 2)

x=8

Step: Substitute 8 for x in y=5x−9:

y=5x−9

y=(5)(8)−9

y=31 (Simplify both sides of the equation)

Answer:

x=8 and y=31

Answer: 6 with a remander of $2

Step-by-step explanation:

Given:

[tex]\angle WXY=82^\circ[/tex]

It underwent a sequence of two rotations around different centers.

To find:

The size of the angle WXY after the sequence of rotations.

Solution:

We know that, rotation is a rigid transformation. It means, the size and shape of the figure remains the same after the rotations. It other words, the figure and its image are congruent after rotation.

So, the measure of angle WXY remains same after the sequence of rotations, i.e.,

[tex]\angle W''X''Y''=82^\circ[/tex]

where, [tex]\angle W'X"Y"[/tex] is the image of [tex]\angle WXY[/tex]  after the sequence of rotations.

Therefore, the size of the angle WXY after the sequence of rotations is 82°.

Answer: 1.588×10−1 (The negative one is small on the top right of the 10)

Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

81

Step-by-step explanation:

angles of a triangle always equal 180, so 41 +58=99, so subtract that from 180 and the remaining angle is 81

Answer:

x = 81°

Step-by-step explanation:

58° + 41° + x = 180°( Sum of all interior angle of a triangle )

or, 99° + x = 180°

or, x = 180°-99°

or, x = 81°

Answer:

Step-by-step explanation:

A. Linear- the add up to 180

B. 3x-5+2x+3+4x+2=180

Answer:

SSS

Step-by-step explanation:

XW = YZ by reflective the line

XY = WZ by the two lines

and XZ = XZ by reflective property of congruence

Answer: SSS = SSS

Step-by-step explanation:

if we look for the 3 aspects of the triangle that we can work with, we only see that they specifically provide us with 2. they are both sides, so we know that it has a least 2 letter S's in the answer. but, we also can see that they share a side. that means that that side is congruent too. so, it is SSS = SSS.

Answer:

x = 45

y = 60

Step-by-step explanation:

2x = 90

2x (1/2) = 90 (1/2)

x = 45

3y - 2y = 90

3y - 2(45) = 90

3y - 90 = 90

3y - 90 (+90) = 90 (+90)

3y = 180

3y (1/3) = 180 (1/3)

y = 60

Quadrilateral

Trapezoid

The given shape in the image is a Trapezoid. The correct option is C.

A trapezoid is a four-sided polygon with at least one pair of parallel sides. The parallel sides are called the bases of the trapezoid, and the non-parallel sides are called the legs.

The height of a trapezoid is the perpendicular distance between the bases. The area of a trapezoid can be calculated by taking the average of the lengths of the two bases and multiplying by the height.

The perimeter of a trapezoid can be found by adding the lengths of all four sides. Some common types of trapezoids include isosceles trapezoids, where the legs have equal lengths, and right trapezoids, where one of the angles between a leg and a base is a right angle.

Trapezoids are commonly used in geometry and in real-life situations, such as construction, architecture, and engineering.

Answer:

Depreciation and Written Down Value for first 5 years of purchase is explained.

Step-by-step explanation:

The Car was purchased for $18000 this will be depreciated at a rate of 20% per year.

Declining Method

Year 1

$18,000 * 20% = $3,600 Depreciation

$18,000 - $3,600 = $14,400 Written Down Value WDV

Year 2

$14,400 * 20% = $2,880 Depreciation

$14,400 - $2,880 = $11,520 WDV

Year 3

$11,520 * 20% = $2,304 Depreciation

$11,520 - $2,304 = $9,216 WDV

Year 4

$9,216 * 20% = $1,843 Depreciation

$9,216 - $1,843 = $7,373 WDV

Year 5

$7,373 * 20% = $1,475 Depreciation

$7,373 - $1,475 = 5,898 WDV
