Question

Which statement about 141° is correct?

A. cos 141 <0
B. tan 141'>0
C. sin 141° <0

Answer 1

`\bold \implies{ \bold{The \: correct \: option \: is \: c) \: sin \: 141° < 0}}`

Step-by-step explanation :

`\bf \longrightarrow \tan141\degree = - (b)/(a) < 0 \\ \\ \bf \longrightarrow \sin141\degree = (b)/(c) > 0 \\ \\ \bf \longrightarrow \cos141 \degree = - (a)/(c) < 0`
