12tan A = 5
वापरलेली संकल्पना:
त्रिकोणमितीय गुणोत्तरांच्या संकल्पनेचा वापर करून,
tanθ = लंब/पाया
cosecθ = कर्ण/लंब
गणना:
12tanA = 5
⇒ tanA = 5/12
tanA = BC/AB
BC/AB = 5/12
ΔABC मध्ये,
पायथागोरस प्रमेयाचा वापर करून,
BC2 + AB2 = AC2
⇒ 52 + 122 = AC2
⇒ 25 + 144 = AC2
⇒ AC = √169
⇒ AC = 13
cosecA = AC/BC
⇒ cosecA = 13/5
∴ cosecA चे मूल्य 13/5 आहे.
