If the measure of is and x = 30, which expression could represent the measure of ?

If the measure of BEC is (2x+3) and x=30, which expression could represent the measure of AED?

(3x-27) will represent the measure of AED.

Step-by-step explanation:

Given:

Measure of  

The value of 'x' =

We have to find the expression which could represent the measure of .

Measure of   (vertically opposite angle property).

Lets measure the numeric value of by plugging the value of 'x' in the expression given.

⇒

⇒

⇒

⇒

⇒

Now plugging the value of 'x' in the expressions given in the options we have to check whether any of the expression is equivalent to or not.

⇒

⇒

⇒

⇒

⇒

So (3x-27) is the appropriate choice.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

im guessing (23,14). hope this : )
