Consider the point $\left(8,\left(-30\right)^\circ\right)$(8,(30)°), in polar coordinates.

Consider the points that have been graphed on the polar grid below.

Convert the point $\left(8,9\right)$(8,9) from rectangular coordinates to polar coordinates $\left(r,\theta\right)$(r,θ), where $0^\circ\le\theta<360^\circ$0°θ<360°. Give each value correct to two decimal places.
