Answer» ON✪:- ∠C = 108° ,FIND ∠a and ∠b.✪ANSWER✪:-from the diagram ,➥OPPOSITE sides are parallel to each other ➥if a quadrilateral has opposite sides ,then it is said to be parallelogram In parallelogram,➥opposite angles are equal so here,∠b = ∠c = 108°∠a = ∠d = X ➠sum of the angles of a quadrilateral = 360°➠∠a + ∠b + ∠c + ∠d = 360°➠ x + 108° + 108° + x = 360°➠ 2x + 216° = 360° ➠ 2x = 360° - 216°➠ 2x = 144°➠ x = 144° / 2 ➠ x = 72°Therefore ,∠a = 72°∠b = 108°∠c = 72°∠d = 108° |
