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°
