its the second one

Step-by-step explanation:

Answer 2

Answer:

∠ 3 and ∠ 2

Step-by-step explanation:

Complementary angles sum to 90°

Since ∠ 1 = 90° and ∠ 1, ∠ 2 and ∠3 lie on a straight line, then

∠ 1 + ∠ 2 + ∠ 3 = 180°, that is

90° + ∠ 2 + ∠ 3 = 180° ( subtract 90° from both sides )

∠ 2 and ∠ 3 = 90°

Since they sum to 90° then

∠ 3 and ∠ 2 are complementary
