If we want to calculate a, then cos(60°) = a/12, but we know that cos(60°) = 1/2,

then 1/2 = a/12 and a = 6

If we want to calculate b, then sin(60°) = b/12, but we know that cos(60°) = (√3)/2

then (√3)/2 = b/12 and b = 6√3

then 1/2 = a/12 and a = 6

If we want to calculate b, then sin(60°) = b/12, but we know that cos(60°) = (√3)/2

then (√3)/2 = b/12 and b = 6√3
