By which angle must AB turn about point A In the clockwise direction so that it coincides with AE?

If AB is rotated 180 degrees clockwise, it will coincide with the line AE

Step-by-step explanation:

The question is incomplete as the diagram for this question in not shown. I have attached the diagram of this question below. Consult it for better understanding.

We have been given a line AB, which we have to rotate clockwise.

We can also see the the angles between any two neighboring line is 90 degrees.

Consider AB, if we rotate in 90 degrees clockwise, the line AB will coincides with the line AD.

If AB is rotated 180 degrees clockwise, the line will coincide with the line AE

If AB is rotated 270 degress, it will coincide with AC

If AB is rotated 360 degrees, it will come back to its original position

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

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.
