S − p hybridization on each Ge atom in planar trans-digermane has been described as sp^1.5 for the GE―Ge sigma bond and sp^1.8 for the Ge―H bond. Calculate the H―Ge―Ge bond angle based on this information. Note that the 4p_x and 4p_y orbitals are proportional to cos(θ) and sin(θ), respectively, and use the coefficients determined in Problem P24.27 to solve this problem.
