Question

3.- Calcula los siguientes ángulos utilizando cada función trigonométrica:


$sen < = \frac{10cm}{12cm} = 0.833 = ? \\ \\ cos < = \frac{9m}{12cm} = 0.75 = ? \\ \\ tan < = \frac{10cm}{9cm} = 1.111 = ?$
​

Answer 1

Seno:

$a = { \sin }^{ - 1} ( \frac{9}{12} )$

a = 0.848

Coseno:

$a = { \cos }^{ - 1} ( \frac{10}{12} )$

a = 0.686

Tangente:

$a = { \tan }^{ - 1} ( \frac{9}{10} )$

a = 0.733
