4.07 Extension: Relating the tangent to the slope of a line

What is the angle of inclination of a line to the $x$x-axis, whose slope is $4$4. Write your answer correct to the nearest degree.

The given line has an angle of inclination of $\theta$θ with the positive $x$x-axis.

The given line passing through the origin makes an angle of $\left(\theta\right)$(θ) with the positive $x$x-axis. The point on the line has coordinates of $\left(5.2,5.72\right)$(5.2,5.72).

Solve for $\theta$θ, giving your answer in degrees correct to four decimal places.
