Question

I attached the question in the image below

Answer 1

`\huge\boxed{\theta=45^o\ \vee\ \theta=225^o}`

Explanation:

`\tan\theta=1`

`\bold{METHOD\ 1}\\\\\text{Use the table in the attachment}\\\\\tan45^o=1\to\theta=45^o\ \vee\ \theta=45^o+180^o=225^o\\\\\bold{METHOD\ 2}\\\\\tan\theta=1\to\tan^(-1)1=\theta\to\theta=45^o\ \vee\ \theta=225^o`

Answer 2

45°

Explanation:

`tan^(-1)(1)` = 45°
