2x 2y 6

2x 2y 6

Input interpretation
triangle | edge lengths 2×2 | 2 y | 2×6
Properties
area | sqrt(-y^4 + 80 y^2 – 1024)
perimeter | 2 (y + 8)
interior angles | ((180 cos^(-1)((y^2 + 32)/(12 y)))/pi° | (180 cos^(-1)(5/3 – y^2/24))/pi° | (180 cos^(-1)(y/4 – 8/y))/pi°)~~(cos^(-1)((0.0833333 (y^2 + 32))/y) radians | cos^(-1)(1.66667 – 0.0416667 y^2) radians | cos^(-1)(0.25 y – 8/y) radians)
interior angle sum | 180° = pi rad~~3.142 rad
