Answer:

∠CDB = 30° and ∠ADB = 80°

Step-by-step explanation:

As we know,

ABCD is a ║gm

∠A = ∠C = 70°(opposite angles of a ║gm are equal)

In Δ BCD,

∠DBC + ∠CDB + ∠BCD = 180°

∠CDB = 180° - 80° - 70°

∠CDB = 30°

Since AB║DC & BD is a transversal

∵ ∠ADB = ∠CBD = 80°(alternate angles of a ║gm are equal)

Thus, ∠ADB = 80°
