Question

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

$sen < = \frac{7cm}{8cm} = 0.875 = ? \\ \\con < = \frac{6cm}{8cm} = 0.75 = ? \\ \\ tan < = \frac{7cm}{6cm} = 1.166 = ?$
​

Answer 1

Seno:

$a = { \sin }^{ - 1} ( \frac{6}{8} )$

a = 0.848

Coseno:

$a = { \cos }^{ - 1} ( \frac{7}{8} )$

a = 0.505

Tangente:

$a = { \tan }^{ - 1} ( \frac{6}{7} )$

a = 0.709
