Hi there


That's easy


All you have to know is that : cot x = cos x / sin x

cot x = .85 / .52 = 1.6346


I hope that's help:)

Any questions ? let me know

sin(x) = 0.52
sin^-1(sin(x)) = sin^-1(0.52)
x = 31.33

cos(x) = 0.85
cos^-1(cos(x)) = cos ^-1(0.85)
x = 31.79

cot(x) = cos(x)/ sin(x)
cot(x) = 0.85/0.52
cot(x) = 1.6346
