An infinitely long slope is made up of a $c-\varphi$ soil having the properties: cohesion $(c)=20 \mathrm{kPa}$, and dry unit weight $\left(\gamma_{d}\right)=16 \mathrm{kN} / \mathrm{m}^{3}$. The angle of inclination and critical height of the slope are $40^{\circ}$ and $5 \mathrm{~m}$, respectively. To maintain the limiting equilibrium, the angle of internal friction of the soil (in degrees) is
