Answer:

$5x+2y+6=0$

Step-by-step explanation:

General equations are in the form $Ax + By + C = 0$

So you can add 6 to both sides to make:

$5x+2y+6=0$

Using the diagram below, identify the relationship of the pair of angles and find the value of x.

ziro4ka [17]

Answer:

The angles are supplementary to each other (their sum is 180 degrees)

x = 62°

Step-by-step explanation:

(2x+10) + 46 = 180

subtract 56 from each side

2x = 124

divide both sides by 2

x = 62°

Al fotocopiar una credencial, primero se amplia al triple y posteriormente la copia resultante se reduce a la mitad. ¿Cual es el

ad-work [718]

Using google translate:
When photocopying a credential, it is first enlarged to triple and subsequently the resulting copy is halved. What is the final effect on the original credential? If the credentials is a rectangle of 10 by 6 cm. What area will you have in the first photocopy? And in the second?

Original: 10 by 6 cm ; Area = length * width = 10 x 6 = 60 cm²

first copy: enlarged to triple
10 x 3 = 30
6 x 3 = 18
30 x 18 = 540 cm²

second copy: halved
30 x 1/2 = 15
18 x 1/2 = 9
15 x 9 = 135 cm²

find the value of each variable in the circle to the right. the dot represents the center of the circle.

gladu [14]

We have been given an image of a circle. We are asked to find the value of each variable.

We can see that angle b corresponds to diameter of circle. We know that the measure of an angle that is inscribed to the diameter of a circle is 90 degrees . Therefore, the value of b will be 90.

we can see that angle is an inscribed angle of arc 99 degrees. We know that measure of an inscribed angle is half the measure of inscribed arc.

$a=\frac{1}{2}\cdot 99$

$a=49.5$

Therefore, the value of a is 49.5 units.

We know that measure of all angles of a triangle is 180 degrees. The measure of 3rd angle will be half the measure of c, so we can set an equation as:

$a+b+\frac{1}{2}c=180$
