Answer:

y = 22

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the angles in the lower triangle and equate to 180°

∠ 1 + 19° + 41° = 180°

∠ 1 + 60° = 180° ( subtract 60° from both sides )

∠ 1 = 120°

∠ 1 and ∠ 2 are vertically opposite angles and are congruent , so

∠ 2 = 120°

Sum the angles in the upper triangle and equate to 180

y + 120 + 38 = 180

y + 158 = 180 ( subtract 158 from both sides )

y = 22
