Question

In the given figure ABCD and BDCE are parallelograms with common Base DC. If BC is perpendicular to BD then find angle BEC.
(Explain step by step)​

Answer 1

Answer:

60 degree is the answer

Step-by-step explanation:

∠ BAC = 30(Given)

∠ ABC = 150(Supplementary angles)

∠ ABD = 150-90 = 600

∠ BDC = 60(Co interior angles)

∠ BEC = 60(Opposite angles)

Answer 2

Answer:

∠ BAC = 30(Given)

∠ ABC = 150(Supplementary angles)

∠ ABD = 150-90 = 60

∠ BDC = 60(Co interior angles)

∠ BEC = 60(Opposite angles)
