Pls as soon as ! will award brainliest and 20 ! also the answer is not 22.5 degrees! find the value of x in each case:

x=0.392 radians

Step-by-step explanation:

Since DE is parallel to AB, then ∠DEA=∠EAB=2x (Alternate angles).            (1)

Also, ∠FEB+∠AEB=180°(Straight line property)

⇒4x+∠AEB=180°

⇒∠AEB=180°-4x                                                           (2)

Also, ∠EBA+∠EBC=180°

⇒∠EBA=180°-6x                                                           (3)

Now, using equations (1), (2) and (3) and the angle sum property in ΔABE, we get

∠EAB+∠AEB+∠EBA=180°

2x+180°-4x+180°-6x=180°

⇒360°-8x=180°

⇒180°=8x

⇒x=22.5°

⇒x=0.392 radians

which is the required value of x.

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
