Respuesta :
[tex] \sin(45 \: degrees) = \: \cos(x) [/tex]
[tex] \frac{ \sin(45 \: degrees) }{cos} = \: x[/tex]
[tex] \frac{ sin}{cos } = tan[/tex]
[tex]therefore \: \: \: \tan(45 \: degrees) = x[/tex]
[tex]but \: \: \: \tan(45 \: degrees) = 1 [/tex]
[tex]therefore \: \: \: x = 1[/tex]
[tex]hope \: this \: helps[/tex]
Answer:
cos 41°
Step-by-step explanation:
this is the correct answer, not the one above.
if entered on the calculator (texas instruments TI-30X2S)
sin (49)= 0.75470958
2nd → cos → 2nd → (-)
which would look like this→ cos-1(0.75470958)
answer= cos 41
