Answer:

X = 66

Step-by-step explanation:

A straight line is equal to 180 degrees so if you have one side of that line you can figure out the inside angle.

Now that you have two of the angles inside the triangle add them up. All the interior angles of a triangle will add to 180. So add up 38 and 76 to get 114. Now do 180 - 114, you should get 66

so x = 66

C = 180 - 104
= 76 degrees
since a straight line is 180 degrees. We minus 104 to 180 to get the other side.

A + B + C = 180
38 + B + 76 = 180
B = 180 - 76 - 38
B = 180 - 114
B = 66 degrees
