Answer:

<EBC = 38

Step-by-step explanation:

A linear pair equals 180 degrees.

So do....

90 + 2x + x + 12 = 180 (collect like terms)

102 + 3x = 180 (subtract 102 on both sides)

-102           -102

3x = 78 (divide both sides by 3)

x = 26

Plug in to get the measure

<EBC = x + 12

26 + 12 = 38

<EBC = 38

Hope this helps ya!!!
