If ∠ 1 and ∠ 2 are vertical angles, ∠ 2 and ∠ 3 are complementary angles, and m∠ 3 = 56 ∘, find m\1.

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle
