Answer: 60/61
Step-by-step explanation:
cosX = adjacent side / hypotenuse
= 11 / 61 __________ given
BY pythagoras theorem,
hypotenuse is 61, adjacent side is 11,
Opposite side must be 61² - 11² = 3600
√3600 = 60 = opposite side
sin X = Opposite side / hypotenuse
= 60/61

Answer
60/61
Step-by-step explanation:
cos x= 11/61
= base /hypotenuse
sin x = perpendicular/hypotenuse
61^2=11^2 + x^2
3721= 121 + x^2
3721-121=x^2
3600=x^2
60=x
