What is an angle?

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

We know that, a ray is a line that continues on forever inn one direction with a point at it's start.

here, we have,

from the diagram, we get,

m∠TUX = 122°

∴m∠VUS = 122°

(vertically opposite angles are equal)

Hence, The solution is, m∠VUS = 122.

James runs 8 laps in 14 minutes. How many laps can he run in one hour and ten minutes?

Answers

Answer: Don't come at me if I'm wrong, but I believe it's 40 laps.

Step-by-step explanation:

First, you need to figure out how many laps James runs in 1 minute and you can do this by dividing the number of laps and minutes (8 laps/14 minutes). This should give you 4/7 laps/minute.

Next, you figure out how many minutes 1 hour and 10 minutes is (just to make things easier) 1 hour and 10 minutes = 70 minutes

Then, you multiple 4/7 and 70 and you get 40 laps.

Answer:

40 laps

Step-by-step explanation:

I just put this into a proportion

so basically i just did 8/14 = ?/70

Then i just worked it like any other problem

8 x 70 then divide 14 and i got 40.

so James ran 40 laps in one hour and tens minutes

NOTE that i turned one hour and ten minutes into minutes

the diagram shows triangle ABD and triangle BCD ABC is a straight line BCD is a quadrilateral triangle angles DAB=25 degrees work out the size of the triangle marked x give a reason for ur answer

Answers

Answer:

25

Step-by-step explanation:

First step is to imagine a line that comes straight down from angle b.

This forms a 90 angle AND perfectly bisects angle b.

A triangle has 180 degrees and the angles we currently know are 25 and 90. add those two together and you get 115.

Subtract that from 180 and you get 65 for one part of angle b.

Since the line perfectly bisects angle b, the other side is also 65.

Now, we have the entire triangle DAB.

Angle B is 65x2=130

Angle A is 25

180 degrees in a triangle

130+25=155 degree that we know.

180-155=25 degrees

The Comfy blanket is regularly priced at $39.99 online on amazon. The website is offering a 10% discount as part of their holiday sales. There is a 6% tax as well. Find the find the final cost.

Answers

Answer:

$38.4

Step-by-step explanation:

Step one:

we are told that the price online is $39.99

and that the discount is 10%

and also tax is 6%

Step two:

discount

let us solve for the deduction first

=10/100*39.99

=$3.99

Tax

=6/100*39.99

=$2.4

The final cost= cost online-10% discount+6% tax

Final cost= 39.99-3.99+2.4

Final cost = $38.4

Zack wants to purchase vinyl to go on his bathroom floor. The vinyl is sold by the foot in length. If the area of his bathroom is 100 square feet, what will one side of the square bathroom measure?

Answers

Answer:

x = 10 feet

Step-by-step explanation:

Given that,

The  area of his bathroom is 100 square feet.

We need to find the one side of the square bathroom.

Let the side be x. The area of a square is given by :

[tex]A=x^2\\\\100=x^2\\\\x=10\ \text{feet}[/tex]

So, the side of the square bathroom is 10 feet.

Which option correctly shows how this formula can be rearranged to isolate x^2?

Options in picture.

Answers

Answer:

A

Step-by-step explanation:

We have:

[tex]\displaystyle m=\frac{x_1-x_2}{y_1-y_2}[/tex]

And we want to isolate x₂.

So, let’s first remove the denominator by multiplying both sides by it:

[tex]\displaystyle m(y_1-y_2)=\frac{x_1-x_2}{y_1-y_2}(y_1-y_2)[/tex]

The right side will cancel. This will leave:

[tex]\displaystyle m(y_1-y_2)=x_1-x_2[/tex]

Now, we can subtract x₁ from both sides. So:

[tex]\displaystyle m(y_1-y_2)-x_1=-x_2[/tex]

Finally, we will multiply both sides by -1. So:

[tex]\displaystyle x_2=-m(y_1-y_2)+x_1[/tex]

Hence, our answer is A.
