Question 16 (OR 2nd question) If 15 cot A = 8, then find value of cosec A. 15 cot A = 8 cot A = 8/15 We know that 1 + cot2 A = cosec2 A 1 + (8/15)^2 = cosec2 A 1 + 64/225 = cosec2 A (225 + 64)/225 = cosec2 A 289/225 = cosec2 A cosec2 A = 289/225 cosec2 A = (17^2/15^2 ) cosec2 A = (17/15)^2 cosec A = 𝟏𝟕/𝟏𝟓
