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.
