Answer 1

Answer:

(a) REQUIRED ANSWER :

${60}^{0}$

From the given figure, ∠BAD = 30o ∠BCD = 30o … [∵opposite angles of parallelogram are equal] Now, let us consider the triangle CBD From angle sum property, ∠DBC + ∠BCD + ∠CDB = 180o 90o + 30o + ∠CDB = 180o 120o + ∠CDB = 180o ∠CDB = 180o – 120o ∠CDB = 60o ∴∠BEC = 60o, because opposite angles of parallelogram are equal.
