$\large \angle QSR = 180 - 150 = 30$

$\large \tan (\angle QSR ) = \tan(30) = ?$

anonymous · Answer

The angle of S must be 30 degrees (180-150), and since R is a right angle, Q is 60 degrees (180 - (90+30)). This is a 30-60-90 triangle, so tan(ang[QSR]) is equal to the one divided by the square root of 3 (1 / sqrt(3)).
