Answer & Explanation:
sin Θ = opp/hyp
cos Θ = adj/hyp
tan Θ = opp/adj
csc Θ = hyp/opp
sec Θ = hyp/adj
cot Θ = adj/opp
1.
sin Θ = opp/hyp = (8√2)/18 = (4√2)/9
cos Θ = adj/hyp = 14/18 = 7/9
tan Θ = opp/adj = (8√2)/14 = (4√2)/7
csc Θ = hyp/opp = 18/(8√2) = (9√2)/(4√2√2) = (9√2)/8
sec Θ = hyp/adj = 18/14 = 9/7
cot Θ = adj/opp = 14/(8√2) = (7√2)/(4√2√2) = (7√2)/8
