Step-by-step explanation:

$\tan \angle A = \frac{3}{6} \\ \\ \therefore \: \tan \angle A = 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} tan(26.565051177 \degree) \\ \\ \therefore \: \angle A = 26.57 \degree$
