Question

HELME PLIS IS A EXAM​

Answer 1

Respuesta:

Crown please

Explicación paso a paso:

csc 45°  = $\sqrt{2}$

csc 30°  =  2

tag 60°  = $\sqrt{3}$

csc 45°  = $\sqrt{2}$

tag 45°  =  1

$(sen30)^2= (\frac{1}{2} )^2 = \frac{1^2}{2^2} = \frac{1}{4}$

$(cos45)^2=(\frac{\sqrt{2}}{2} )^2 = \frac{(\sqrt{2}^2)}{2^2} = \frac{2}{4} \\=>\frac{1}{2}$

sen 30° = $\frac{1}{2}$
