Does anyone know how to solve this ?

The measure of the angle x in the right triangle is 67 degrees.

A right angle triangle has one of its angles as 90 degrees.

The sum of angle in a triangle is 180 degrees.

Therefore,

x + 90 + 23 = 180

x + 113 = 180

x + 113 - 113 = 180 - 113

x = 67°

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

12+50+40+22=124

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

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.

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:

3x = 3 + 2y -------------> 3x - 2y = 3 {subtracted 2y from each side of top equation}

(-4/3)x + y = -2/3 ------> -4x + 3y = -2 {multiplied bottom equation by 3}

3x - 2y = 3 ------> 12x - 8y = 12 {multiplied top equation by 4}

-4x + 3y = -2-----> -12x + 9y = -6 {multiplied bottom equation by 3}

12x - 8y = 12

-12x + 9y = -6

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

y = 6 {added the two equations}

3x = 3 + 2y {original top equation}

3x = 3 + 2(6) {substituted 6, in for y, into top equation}

3x = 3 + 12 {multiplied}

3x = 15 {added}

x = 5 {divided each side by 3}

x = 5 and y = 6
