Answer:

20 cm

Step-by-step explanation:

So from the problem we get that the two sides of the rctangle are 16 cm 12 cm which are base perpendicular of the right angle triangle. H = 20 cm. So the diagonal of the rectangle = 20 cm.

Answer:

20 cm

Step-by-step explanation:

Here's your solution

=> length of rectangle = 16 cm

=> width of rectangle = 12 cm

=> Diagonal of rectangle = √(l^2 + w^2 )

=> Diagonal = √(16^2 + 12^2)

=> Diagonal = √(256 + 144)

=>. Diagonal = √400

=> Diagonal = 20 cm

Answer:

Solution (4,3)

Step-by-step explanation:

2x-7y= -13

(8x-7y=11)x-1

2x-7y= -13

-8x +7y= -11

[tex]\frac{-bx}{-6} =\frac{-24}{-6}[/tex]

x= 4

__________

2x-7y= -13

2(4)-7y=-13

8-7y= -13

subtract 8 from both sides

[tex]\frac{-7y}{-7} =\frac{-21}{-7}[/tex]

divide by -7

y= 3

Answer:

X = 3.01

Step-by-step explanation:

To solve for x, you first need to get x by itself. So you would minus 19.95 from both sides. Which would then be

5x = 15.05

Again x is not by itself so you would divide both sides by 5, the eqation would then be

x = 3.01

Which is the answer. If you want you can double check your work by putting the answer back in the eqaution.

5(3.01) + 19.95 = 35

If the statement is true that means you have the right answer

15.05 + 19.95 = 35

35 = 35

We are correct! Hope this helps with your question and how to do others like it.

Answer:

162 degrees

Step-by-step explanation:

We can look at this problem like a circle, the figure is essentially a circle and a circle is equal to 360 degrees. Using this and knowing that the box is equal to 90 degrees you simply subtract 90+108 from 360 to get a.  

Answer:

FIND X AND PLUG IT IN

You basically put x+12+2x+3+90=180 and solve for x. Then when you find x plug it in x+12 to find a and 2x+3 to find c.

Answer:

angle A is 37°

angle C is 53°

Step-by-step explanation:

The angles x+12 and 2x+3 add to 90°,  because there is already a right angle in the triangle and the total angles in a triangle add to 180°

x+12+2x+3=90

3x+15=90

3x=75

x=25

Knowing x=25°, we can substitute it back into angle A and C.

A: 25+12=37°

C: 2(25)+3=50+3=53°

Answer:

No solution

Step-by-step explanation:

When we take the 5/2 x to the other side, 4x and 4x cancels out. We get 7=0 which is incorrect. Therefore, x has no solution.

Answer: 11

Students have both a brother and a sister

Step-by-step explanation:

I don't think probability should be used for this question because the answer is quite clear

So in a class of 25 students

5 students don't have a sibling

So 25-5=20

Total number of siblings=14+17=31 siblings in total

So 20 people have 31 siblings

31-20=11

So the answer should be 11

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. The probability that a student who has a brother also has a sister is 11/25.

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events that belong to E, and total cases are the size of the sample space.

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings.

So in a class of 25 students

5 students don't have a sibling

then, 25-5=20

Total number of siblings = 14+17

= 31 siblings in total

So, 20 people have 31 siblings

= 31 - 20

= 11

So, the probability that a student who has a brother also has a sister

= 11/ 25.

Answer:

B

Step-by-step explanation:

An algebraic expression represents the number of degrees of rotation about the polygon’s center that would carry the polygon onto itself is 360 / a.

A polygon is a closed figure made up of three or more line segments connected end to end.

A polygon in the plane has rotational symmetry when the figure is mapped onto itself by rotating between 0 and 360° about its center.

So, we need to find the number of symmetrical lines a regular polygon.

A regular polygon with a sides has n lines of symmetry and order of symmetry.

Then, let a be the number of symmetrical line lines

Answer:

the slope of both lines are the same.

Step-by-step explanation:

Given the following segment of the Quadrilateral EFGH on a coordinate  Segment FG is on the line 3x − y = −2,

segment EH is on the 3x − y = −6.

To determine their relationship, we can find the slope of the lines

For line FG: 3x - y = -2

Rewrite in standard form y = mx+c

-y = -3x - 2

Multiply through by-1

y = 3x + 2

Compare

mx = 3x

m = 3

The slope of the line segment FG is 3

For line EH: 3x - y = -6

Rewrite in standard form y = mx+c

-y = -3x - 6

Multiply through by-1

y = 3x + 6

Compare

mx = 3x

m = 3

The slope of the line segment EH is 3

Hence the statement that proves their relationship is that the slope of both lines are the same.

The slope of the lines is the same, the line segments FG and EH are parallel to each other and are the opposite sides of the quadrilateral.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is constant.

The slope of the line segment FG can be found by comparing the equation with the equation of the line. Therefore,

y = mx + c

-2 = 3x - y

- 2 - 3x = -y

y = 3x + 2

Thus, the slope of the equation is 3.

The slope of the line segment EH can be found by comparing the equation with the equation of the line. Therefore,

y = mx + c

3x - y = -6

-y = 6 - 3x

y = 3x+6

Thus, the slope of the equation is 3.

Since the slope of the lines is the same, the line segments FG and EH are parallel to each other and are the opposite sides of the quadrilateral.
