Download Solution PDFఇచ్చినది:
12tan A = 5
ఉపయోగించిన భావన:
త్రికోణమితి నిష్పత్తుల భావనను ఉపయోగించి,
tanθ = లంబం/ఆధారం
cosecθ = కర్ణం/ లంబం
గణన:
12tanA = 5
⇒ tanA = 5/12
tanA = BC/AB
BC/AB = 5/12
ΔABC లో,
పైథాగరస్ సిద్ధాంతాన్ని ఉపయోగించి,
BC2 + AB2 = AC2
⇒ 52 + 122 = AC2
⇒ 25 + 144 = AC2
⇒ AC = √169
⇒ AC = 13
cosecA = AC/BC
⇒ cosecA = 13/5
∴ cosecA విలువ 13/5.
