Which of the following is the best definition of vertical angles?

Mathematics

Lilit [14]2 years ago

Step-by-step explanation:

Very quick and effortless example of vertical angles in the attached image. When 2 straight lines intersect, the 2 angles opposite each other at that point are vertical angles, and they are always congruent.

I'd say it's the 3rd option:

"Vertical angles are a pair of non-adjacent angles formed by two intersecting lines."

but any of the first three could be technically true really. Adjacent angles are 2 angles that share a side, and vertical angles cannot share one.

How can you find this distance (-3,7),(0,4) in words

Bezzdna [24]

Answer:

The distance between these two given points is:

$3\sqrt{2}$

Step-by-step explanation:

We are given two points:

(-3,7),(0,4)

The distance between two points (a,b) and (c,d) is given by the distance formula as:

$\sqrt{(c-a)^2+(d-b)^2$

similarly we can find the length of a line segment by considering the distance between the end points of the line segment.

So here (a,b)=(-3,7)

and (c,d)=(0,4).

Hence distance between these two points is given by:

$\sqrt{(0-(-3))^2+(4-7)^2}=\sqrt{(3)^2+(-3)^2}=\sqrt{9+9}\\ \\=\sqrt{18} \\\\=3\sqrt{2}$

There are 9 seniors.

Although there are several ways of solving this problem, I just did what was easiest for me in my head. I divided 36 by 4, which gave me 9.

What is the area of the shaded region?

USPshnik [31]

Answer:

Area of the whole rectangle = 11 x 12

= 132 cm^2

Area of the circle = πr^2

= 3.14 x 2 x 2

= 12.56 cm^2

Area of the shaded region = area of rectangle - area of circle

= 132 - 12.56

= 119.44 cm^2

Hope this helps!

Please help i need the answer and how you did it

Arturiano [62]

1. First, do 12 x 8 to work out the area of the rectangle, which is 96ft.
Then, to work out the area of a circle, you use the equation πr² to help you. You would multiply π by the radius², which is 16. Now you have just worked out the area of a circle, but not a semicircle, so you would have to divide your answer by two to get the area of this, which would be 25.13 (rounded to 2 d.p).
To get the area of the whole shape, you just have to add the two totals together.
25.13 + 96 = 121.13ft.
Remember to put the units there, or you can lose marks.

Try your best with the next questions! I have written the formulas for the other shapes to help you work out the answers.

Area of a square = Multiply sides together.
Area of rectangle = Multiply width by length.
Area of a circle = Multiply π by the radius².
Area of a semicircle = Multiply π by the radius², and the divide by two.
Area of a triangle = Multiply the base by the height, and then divide by two.

Really hope this helps!
