Answer:
see explanation
Step-by-step explanation:
• The diagonals bisect each other at right angles, then
∠ 2 = ∠ 3 = 90°
∠ 1 = 180° - (90 + 52)° ← angle sum of a triangle
∠ 1 = 180° - 142° = 38°
• Diagonals bisect the endpoints, then
angle at vertex with ∠ 1 = 76° and
angle at vertex with ∠ 4 = 76°, thus
∠ 1 = ∠ 4 = 38°
In conclusion
∠ 1 = 38°, ∠ 2 = 90°, ∠ 3 = 90°, ∠ 4 = 38°
