The given functions are
[tex]\begin{gathered} y=tan\frac{\theta}{4} \\ \\ y=cos(\theta+120) \end{gathered}[/tex]
The red graph represents the 1st function
The blue graph represents the 2nd function
They intersected at point (43.4 degrees, 0.192)
There is only one point of intersection between the 2 graphs
The answer is
[tex](43.4^{\circ},0.192)[/tex]
To find the points on the red graph
Substitute x by 0, 90 degrees (pi/2), 180 degrees (pi), and 270 degrees (3/2pi)
