Explicación paso a paso:
1.
Aqui empleamos las razones trigonometricas para angulos complementarios
Sex = cos (90 - x) por ejemplo Sen40 = cos x
x = 90 - 40 .... x= 50
a) sen 3x = cos 6
3x+6=90
3x= 84
x= 28
b) sen (x+y) = Cos (2x - y)
x+y+2x-y =90
3x =90
x= 30
c) Tg ( 3x+y) = Ctg ( x-y)
3x+y+x-y=90
4x=90
×= 22.5
d) Sec (x+35) = Csc ( x+15)
x+25+x+15 =90
x= 20
e) sec ( 2x+y-z) = Csc ( x-y+z)
2x+y-z+x-y+z=90
3x=90
x=30
