Inner Diagonal of Concave Quadrilateral Solution

Follow our step by step solution on how to calculate Inner Diagonal of Concave Quadrilateral?

FIRST Step Consider the formula

d Inner = \sqrt{{S Second Outer}^{2} + {S Second Inner}^{2} - (2 \cdot S Second Outer \cdot S Second Inner \cdot \cos (∠ Third Acute))}

Next Step Substitute values of Variables

∴

d Inner = \sqrt{{5m}^{2} + {2m}^{2} - (2 \cdot 5m \cdot 2m \cdot \cos (55°))}

Next Step Convert Units

∴

d Inner = \sqrt{{5m}^{2} + {2m}^{2} - (2 \cdot 5m \cdot 2m \cdot \cos (0.9599rad))}

Next Step Prepare to Evaluate

∴

d Inner = \sqrt{5^{2} + 2^{2} - (2 \cdot 5 \cdot 2 \cdot \cos (0.9599))}

Next Step Evaluate

∴

d Inner = 4.18670171769809m

LAST Step Rounding Answer

∴

d Inner = 4.1867m
