Assume that the radiation intensity of a horn antenna is given by $U(\theta, \phi) = \begin{cases} U_0 \cos^7(\theta), & 0 \le \theta < 90^\circ, \forall \phi \\ 0, & \text{otherwise} \end{cases}$ where $U_0$ is a constant. At what angle (value of $\theta$) is the directivity at a value that is 1/2 of its maximum value? Type your answer in degrees to one place after the decimal.
