Question

hello can you help me solve this plane trigonometry question please and thank you for your time if you are reading this

Answer 1

We have the following:

adjacent leg = a

hypotenuse = h

`\cos \theta=(a)/(h)`

replacing:

`\begin{gathered} \cos \theta=(11)/(12) \\ \cos \theta=0.916 \\ \theta=\cos ^(-1)(0.916) \\ \theta=23.56 \end{gathered}`

The angles is 23.6°
