-- "Perimeter" means all the way around, all four sides.
-- That's two lengths and two widths.
-- So one length and one width is half of the perimeter.
-- If the perimeter is 16-ft, then one length + one width is 8-ft.
-- If the width is 5-ft, then the length is (8 - 5) = 3-ft.

Answer:
11/12
Step-by-step explanation:
tan θ = sin θ / cos θ
cos θ = sin θ / tan θ
cos θ = (√23/12) / (√23/11)
cos θ = (√23/12) × (11/√23)
cos θ = 11/12
