Answer 2

Answer:

a) x = 130

Step-by-step explanation:

Extend line segment CD to join line segment AB at point P.

∠CPB = ∠CAP + ACP {Exterior angle theorem for a triangle ΔCAP}

⇒ ∠CPB = 55° + 30°

⇒ ∠CPB = 85°

∠CDB = ∠CPB + ∠PBD {Exterior angle theorem for a triangle ΔCPB}

∠CDB = 85° + 45°

⇒ ∠CDB =x = 130°
