A wing of $15 \mathrm{~m}$ span with elliptic lift distribution is generating a lift of $80 \mathrm{kN}$ at a speed of $90 \mathrm{~m} / \mathrm{s}$. The density of surrounding air is $1.2 \mathrm{~kg} / \mathrm{m}^{3}$. The induced angle of attack at this condition is_________degrees (round off to two decimal places)
