Question

1. Lines k, m and n are all parallel.
What is the sum of < 1 and < 2?

Answer 1

80 degrees.

Step-by-step explanation: Because the 3 lines are parallel, angle 1 = 50. Because alternate angles in parallel lines are equal, we can use the equation 180-150=30. So angle 2=30. 30+50=80, so the sum it 80 degrees.
