Step-by-step explanation:
x cos θ + y sin θ = x cos β + y sin β
<em>Let's say x = cos A, and y = sin A.</em>
cos A cos θ + sin A sin θ = cos A cos β + sin A sin β
<em>Use angle sum formula.</em>
cos(A − θ) = cos(A − β)
A − θ = ±(A − β)
A − θ = β − A
2A = θ + β
A = (θ + β) / 2
cot A = cot((θ + β) / 2)
x/y = cot((θ + β) / 2)

Answer:
s / ( 2 pi * h) = r
Step-by-step explanation:
s = 2 * pi * r * h
Divide each side by 2 * pi * h
s / 2 pi h= 2 * pi * r * h/ ( 2 pi h)
s / ( 2 pi * h) = r
