Explain how to determine that you have constructed an accurate copy of an angle

1 answer:

5 0

You have determined that you have constructed an accurate copy of an angle because if you just draw a ray, and measure the angle of the original angle, use that same compass setting and put it on the vertex of the ray that you just drew. Make an arc that intersects the ray. At that intersection point that you just made, draw another arc with that same compass setting, through the other arc, making intersecting lines. At that final intersection point, that's where you draw your line through. Now you have constructed an accurate copy of an acute angle.

a rectangle has a perimeter of 204 feet. Its length is six feet longer that twice its width. find the dimensions

frutty [35]

Answer:

The length of the rectangle is 70 cm

The width of the rectangle is 32 cm

Step-by-step explanation:

Given:

perimeter of the rectangle = 204 feet

Its length is six feet longer that twice its width

To Find:

The dimensions of the rectangle = ?

Solution:

Let the width of the rectangle be x

Then its length is six feet longer that twice its width.

That is length = 6 + 2x

Now we know that the perimeter of the rectangle is

perimeter = 2(length + width)

204 = 2(6+2x+x)

204 = 2(6+3x)

204 = 12 +6x

204 - 12 = 6x

192 = 6x

x = $\frac{192}{6}$

x = 32

Thus the width is 32 cm

Its length is

=6 + 2x

=6 + 2(32)

=6 + 64

= 70 cm

If ABC ~ DEC, find the values of x and y. help me pleaseee!!!

Savatey [412]

Answer:

X = 8

Y = 35

Step-by-step explanation:

All you need to do to solve this problem is use the Pythagorean Theorem $(a^{2} +b^{2} =c^{2} )$

The leg of the triangle are A and B and C represents the hypotenuse. All you need to do is plug in the values into the equation and there u have it.

I have created an image for you to follow.

Find the endpoint of the line segment

blondinia [14]

Answer:

(29,-13)

Step-by-step explanation:

You can tackle this for x and y coordinate separately.

For x, the line starts at -9 and is halfway at 10. The distance between -9 and 10 is 19 so it has another 19 to go, which puts the endpoint at 10+19=29.

Same for y: from 7 to -3 is 10 down, another 10 to go, puts you at -13.

Formula: x,y of midpoint is ((x1+x2)/2, (y1+y2)/2)

How do you find the additive inverse of an integer? i need help on my math homework. I do not understand this question. Anyone k

lilavasa [31]

The additive inverse of an integer is a number, when added to the integer, equals 0. Basically, its the opposite number.

Example : Find the additive inverse of 5
5 + ? = 0 .... the additive inverse would be -5...because 5 + (-5) = 5 - 5 = 0.

The additive inverse of 3 = -3
additive inverse of - 4 = 4
additive inverse of 6 = -6
