$0.47 π$ $0.47pi$
$85^{\circ} 24$ $85^@24$

Explanation:

Use calculator:
tan x = 12 --> $x = 85^{\circ} 24$ $x = 85^@24$
Convert x to radians:
$180^{\circ} - \to π$ $180^@ --> pi$
$1^{\circ} - \to \frac{π}{180}$ $1^@ --> pi/180$
$85^{\circ} 24 - \to \frac{(85.24) π}{180} = 0.47 π$ $85^@24 --> ((85.24)pi)/180 = 0.47pi$
