Question

I need help solving this plz

Answer 1

We can rewrite
`cot(45^(\circ)+2\theta)` as
`tan(90^(\circ)-(45^(\circ)+2\theta)`
`\Rightarrow`
`cot(45^(\circ)+2\theta)` equals to
`tan(45^(\circ)-2\theta)`.

Now we need to take an
`arctan` of both sides.


`\theta = 45^(\circ)-2\theta+180n^(\circ) \\3\theta = 180n^(\circ)+45^(\circ) \\\theta = 60n^(\circ)+15^(\circ) \\\theta = 15^(\circ)`

Your answer is
`15^(\circ)`.
