All the angles of a triangle add up to 180 degrees.
30+39+<4= 180
69+<4= 180
Subtract 69 on both sides.
<4= 111 degrees
<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.
111+<1= 180
<1= 69 degrees
I hope this helps!

M∠2 = 39, M∠3 = 30
M∠4 = 180 - (M∠2 + M∠3)
M∠4 = 180 - (39 + 30)
M∠4 = 180 - 69
M∠4 = 111
180 - M∠4 = M∠1
180 - 111 = M∠1
M∠1 = 69
M∠1 = 69
C is your answer
hope this helps
