Question

si tan x = 0,3333....(x; agudo)calcular sen2x​

Answer 1

Respuesta Sen 2x = 3/5

Explicación paso a paso:

Tan x = 0,333... = 1/3

Entonces

CO = 1, CA = 3, h = $\sqrt{10}$

Sen 2x = 2 Sen x . Cos x

$Sen 2x = 2 \frac{\sqrt{10} }{10} . \frac{3\sqrt{10} } {10}\\Sen 2x = \frac{(6) 10^{1}}{10^{2} } \\ Sen 2x = 60/100 = 6/10\\Sen 2x = 60/100 = 3/5$
