Question

if tan A=5/12 find cosec B​

Answer 1

Answer:

cosec A = 13/5

Step-by-step explanation:

tanA = 5/12

cotA = 1/tanA = 1/(5/12) = 12/5

By the formula,

cosec²A - cot²A = 1

cosec²A - (12/5)² = 1

cosec²A - 144/25 = 1

cosec²A = 1 + 144/25

cosec²A = (25+144)/25

cosec²A = 169/25

cosecA = √(169/25) = 13/5
