Since m || n, angle of line m is also t(corresponding angles)
We know that the sum of angles on a straight line is 180 degree.

s + t = 180
But we are given s = t+30
So, 2t + 30 = 180
2t = 150
t = 75(Option C)

Because the 2 lines are parallel we know that the angle next to s is t. Therefore s+t=180

Now we have 2 equations 2 unknowns, s+t=180 and s=t+30 => s=180-t, now substitute in the 2nd equation for s and we get the following: 180-t=t+30 => 2t=150 => t=75

Answer is C
