Question

calcula csc²a.csc²b
​

Answer 1

Respuesta:

9

Explicación paso a paso:

Sabemos que:

Csc= Hipotenusa/C.O

Csc²(a)= (x/6)²

Csc²(B)= (18/x)²

Csc²(a).Csc²(B)= (x/6)²(18/x)²

$\frac{ {x}^{2} . {18}^{2} }{ {6}^{2} .{x}^{2} }$

$\frac{ {18}^{2} }{ {6}^{2} }$

$\frac{ {(3.6)}^{2} }{ {6}^{2} }$

$\frac{ {3}^{2} {6}^{2} }{ {6}^{2} }$

${3}^{2}$

$9$
