1. Rotating a line to equal intercepts ●●●○○ 50 ptsThe line $y=10-2x$ is rotated anticlockwise about the origin through an angle $\theta$, where $0 \le \theta \le 90$ (in degrees). The image has $x$-intercept $(p,0)$ and $y$-intercept $(0,q)$. Determine $\theta$ such that $p=q$. Round to two decimal places.
