Final answer:
To find all possible values of ∠ZH in triangle AHIJ, subtract 75 degrees from 180 degrees and divide the result by 2.
Step-by-step explanation:
To find all possible values of ∠ZH in triangle AHIJ, we can use the fact that the sum of angles in a triangle is 180 degrees and the property of corresponding angles in congruent triangles. Given that ∠2J = 75°, we can determine the measure of ∠ZH by subtracting 75 degrees from 180 degrees and dividing the result by 2. This is because ∠ZH and ∠2J are corresponding angles in congruent triangles. Therefore, ∠ZH = (180 - 75) / 2 = 52.5°.
