Angle D of Cyclic Quadrilateral Solution

Follow our step by step solution on how to calculate Angle D of Cyclic Quadrilateral?

FIRST Step Consider the formula

∠D = \arccos (\frac{{S d}^{2} + {S c}^{2} - {S a}^{2} - {S b}^{2}}{2 \cdot ((S d \cdot S c) + (S b \cdot S a))})

Next Step Substitute values of Variables

∴

∠D = \arccos (\frac{{5m}^{2} + {8m}^{2} - {10m}^{2} - {9m}^{2}}{2 \cdot ((5m \cdot 8m) + (9m \cdot 10m))})

Next Step Prepare to Evaluate

∴

∠D = \arccos (\frac{5^{2} + 8^{2} - 10^{2} - 9^{2}}{2 \cdot ((5 \cdot 8) + (9 \cdot 10))})

Next Step Evaluate

∴

∠D = 1.9324764463028rad

Next Step Convert to Output's Unit

∴

∠D = 110.722744381611°

LAST Step Rounding Answer

∴

∠D = 110.7227°
