Answer:
x = 63 degrees.
Stepbystep explanation:
So first, 2y  30 = 68 degrees.
It is because of alternative interior angles.
2y  30 = 68
2y = 98 Move the 30 to the other side
98/2 = 49 So, y = 49
So in a triangle, the 3 angles equal 180 degrees.
So you do 49 + 68 = 117 degrees. You do this, because the 2 angle not including x is 49 and 68
Then you subtract 117 from 180
180  117 = 63 degrees. You do this because the 3 angles of a triangle equal 180 degrees.
So x = 63 degrees

Answer:
x = 63
Stepbystep explanation:
Since AB and CD are parallel lines, then
2y  30 = 68 ( corresponding angles )
Add 30 to both sides
2y = 98 ( divide both sides by 2 )
y = 49
The third angle in the triangle = 68 ( alternate angles )
The sum of the 3 angles in the triangle = 180°, that is
x + y + 68 = 180 ← substitute value of y
x + 49 + 68 = 180
x + 117 = 180 ( subtract 117 from both sides )
x = 63
