WebMay 10, 2024 · Shwetank Mauria. May 10, 2024. As adjacent angles of a parallelogram are supplementary and opposite angles are equal, if one angle is obtuse, adjacent angle would be acute and opposite angle would be obtuse. Hence, a parallelogram can have no more than two obtuse angles. WebFeb 2, 2024 · The answer is 75. We use the formula that says the area is equal to ½ times the product of the lengths of the diagonals times the sine of the angle between them. As our diagonals are perpendicular, the angle between them is 90° and sin 90° = 1. Hence, the calculation we need to perform is ½ × 10 × 15 = 75. Hanna Pamuła, PhD. greenacre park swadlincote
