Answer:

Properties of a rhombus used to solve the following

Opposite angles are congruent
Diagonals are angle bisectors
Diagonals are perpendicular to each other
Adjacent angles are supplementary

(30)

∠2 = ∠3 = ∠5 = 27°
∠1 = ∠4 = 180° - (2*27°) = 126°

(31)

∠4 = 70°
∠1 = ∠2 = ∠3 = ∠5 = 1/2(180° - 70°) = 1/2(110°) = 55°

(32)

∠1 = ∠2 = ∠5 = 90° - 26° = 64°
∠3 = 26°
∠4 = 90°
