Answer 1

Resposta:

Explicação passo a passo:

$sen\alpha =\frac{catop}{hip} \\cos\alpha =\frac{cat adj}{hip} \\tag\alpha =\frac{catop}{catadj} \\\\\\sen\alpha=\frac{x}{9} \\sen65=\frac{x}{9} \\0,91=\frac{x}{9} \\x=0,91x9=8,19\\\\Cos\alpha=\frac{y}{9} \\0,42=\frac{y}{9} \\y=0,42x9\\y= 3,78\\\\\\Tg\alpha =\frac{8,19}{3,78} \\Tg= 2,16$
