Answer:
The measure of angle 1 is 30°
Step-by-step explanation:
The supplement of 150° is 30°
180-150=30
and if a line goes through two parallel lines, the corresponding angles will be congruent.
30°
the angle in front of the angle 150° has the same value as m∠1, so you just have to subtract 150° by 180° since they both add up to a straight angle.
the angle 150° equals to the one next to m∠1
I hope that helps!
