Obtuse Angle of Rhombus given Long Diagonal Solution

STEP 0: Pre-Calculation Summary

Formula Used

Obtuse Angle of Rhombus = acos(1-Long Diagonal of Rhombus^2/(2*Side of Rhombus^2))
∠_Obtuse = acos(1-d_Long^2/(2*S^2))
This formula uses 2 Functions, 3 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
acos - The inverse cosine function, is the inverse function of the cosine function. It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., acos(Number)

Variables Used

Obtuse Angle of Rhombus - (Measured in Radian) - Obtuse Angle of Rhombus is the angle inside the Rhombus which is greater than 90 degree.
Long Diagonal of Rhombus - (Measured in Meter) - The Long Diagonal of Rhombus is the length of line joining the acute angle corners of a Rhombus.
Side of Rhombus - (Measured in Meter) - The Side of Rhombus is the length of any of the four edges.

STEP 1: Convert Input(s) to Base Unit

Long Diagonal of Rhombus: 18 Meter --> 18 Meter No Conversion Required
Side of Rhombus: 10 Meter --> 10 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

∠_Obtuse = acos(1-d_Long^2/(2*S^2)) --> acos(1-18^2/(2*10^2))

Evaluating ... ...

∠_Obtuse = 2.23953902999727

STEP 3: Convert Result to Output's Unit

2.23953902999727 Radian -->128.31613447369 Degree (Check conversion here)

FINAL ANSWER

128.31613447369 ≈ 128.3161 Degree <-- Obtuse Angle of Rhombus
