Question

Calcular : K = ( csc 53 + tan 37 ) ( sec 2 45 + tan 45 )

Answer 1

Respuesta:

K =  - 3

Explicación paso a paso:

Csc 53° = 1.2521 ,  tan 37° = 0.7536 ,  sec 245° = -2.3662 , tan 45° = 1

K = ( csc 53° + tan 37° ) ( sec 245° + tan 45° )

K = ( 1.2521 + 0.7536 ) ( -2.3662 + 1 ) = ( 2.0057 ) ( -1.3662 )

K =  - 2.74

K = -3
