Question

PLEASE HELP

Find tan (QRS)

Answer 1

because

TSR + QSR = 180⁰

<=> 150⁰ + QSR = 180⁰

=> QSR = 30⁰

so

`\tan(qsr) = \tan(30) = ( √(3) )/(3)`

Answer 2

A.
`(\sqrt 3)/(3)`

Explanation:

`m\angle QSR = 180\degree - 150\degree \\ (Linear \: pair\: \angle s) \\ \\m\angle QSR = 30\degree \\ \\ \tan( \angle QSR) = \tan \: 30 \degree \\ \\ = (1)/( √(3) ) \\ \\ = ( √(3) )/(3)`
