Question

ayudenme porfavor :c

Answer 1

Explicación paso a paso:

1.

e)

2.

Sen 3x csc 54 = 1

$\sin3x = \frac{1}{ \frac{1}{sen \: 54} }$

$3x = \frac{1}{ \frac{1}{54} } = 54$

3x = 54

x = 18

3.

$\tan3x = \frac{1}{ \frac{1}{ \tan( x+ 40) } }$

tan 3x = tan (x + 40)

3x = x + 40

2x = 40. =====> x = 20

cos 3x

cos 60= 1/2

4.

d)

cos (2x - 10°) = cos (x + 30°)

2x - 10 = x + 30

x = 40
