Answer:
∠ 1 = 67° , ∠ 2 = 41° , ∠ 3 = 72°
Step-by-step explanation:
∠ 1 and ∠ 4 are corresponding angle and are congruent , then
∠ 1 = ∠ 4 = 67°
∠ 2 and ∠ 5 are alternate angles and are congruent , then
∠ 2 = ∠ 5 = 41°
The sum of the 3 angles in the triangle = 180°
sum the angles and equate to 180°
∠ 3 + 67° + 41° = 180° , that is
∠ 3 + 108° = 180° ( subtract 108° from both sides )
∠ 3 = 72°
