Question

Can someone help me with this? I don't understand how to do these & I need to know the answers.

Answer 1

The interior angles of a triangle add up to 180 degrees.

1. 180 - (117 + 33) =
     180 - 150 =
      30....so < 1 = 30

2. 180 - (57 + 33) =
     180 - 90 =
      90....so < 1 = 90
