Long Edge of Parallelogram given Diagonals and Obtuse Angle between Diagonals Solution

Follow our step by step solution on how to calculate Long Edge of Parallelogram given Diagonals and Obtuse Angle between Diagonals?

FIRST Step Consider the formula

e Long = \frac{1}{2} \cdot \sqrt{{d Long}^{2} + {d Short}^{2} - (2 \cdot d Long \cdot d Short \cdot \cos (∠ d(Obtuse)))}

Next Step Substitute values of Variables

∴

e Long = \frac{1}{2} \cdot \sqrt{{18m}^{2} + {9m}^{2} - (2 \cdot 18m \cdot 9m \cdot \cos (130°))}

Next Step Convert Units

∴

e Long = \frac{1}{2} \cdot \sqrt{{18m}^{2} + {9m}^{2} - (2 \cdot 18m \cdot 9m \cdot \cos (2.2689rad))}

Next Step Prepare to Evaluate

∴

e Long = \frac{1}{2} \cdot \sqrt{18^{2} + 9^{2} - (2 \cdot 18 \cdot 9 \cdot \cos (2.2689))}

Next Step Evaluate

∴

e Long = 12.3820756089027m

LAST Step Rounding Answer

∴

e Long = 12.3821m
