Question

Si BC=4tan45° , calcule BD en términos de alfa​

Answer 1

RESOLUCIÓN:

$BC = 4tan45° \\ BC = 4 × 1 \\ BC = 4$

$\frac{BA}{4} = tan \alpha \\ BA = 4tan \alpha$

$\frac{BD}{4tan \alpha } = tan \alpha \\ BD = tan \alpha \times 4tan \alpha \\ BD = 4tan {}^{2} \alpha$

RESPUESTA:

$D) \: 4tan {}^{2} \alpha$
