Using the image below, identify the angles that are vertical angles, list the angles that are linear pairs, and then solve for , , and .

Vertically opposite angles are

Linear pair of angles are

,

Step-by-step explanation:

Given: image

To find: vertical angles, the angles that form linear pairs, value of x, y and z

Solution:

If two lines intersect each other then the vertically angles formed are equal.

Two adjacent angles are said to be linear if their sum is .

From the given image,

vertically opposite angles are

Linear pair of angles are

As vertically opposite angles are equal,

As sum of angles that form a linear pair is ,

Also, as x and z are vertically opposite angles,

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
