Question

please someone solve this​

Answer 1

Answer:

Angle is -53.80

$\pi \div 12 = 15$

$3 \tan( - 15) = \tan( \beta + 15)$

$3 \times ( - 2 + \sqrt{3} ) = \tan( \beta + 15)$

$- 6 + 3 \sqrt{3} = \tan( \beta + 15)$

take inverse tan on both sides.

Therefore,

$- 38.80 = \beta + 15$

$\beta = - 53.80$
