Dear Student ,

Please find below the solution to the asked query :

∠ BAC = 30 ° ∠ BAC = ∠ BCD = 30 ° (Opposite angles of parallelogram are equal) ∠ EBC = ∠ BCD = 30 ° (BE ∥ DC, Alternate interior angles are equal) ∠ CBD = 90 ° (Since BC ⊥ BD) ∠ ECB = ∠ CBD = 90 ° (CE ∥ DB, alternate interior angles are equal) In ∆ BCE, Using Angle Sum Property ∠ EBC + ∠ ECB + ∠ BEC = 180 ° 30 ° + 90 ° + ∠ BEC = 180 ° 120 ° + ∠ BEC = 180 ° ∠ BEC = 180 ° - 120 ° ∠ BEC = 60 ° ANS . . .
