Question

If 15 cot A = 8, then find value of cosec A.​

Answer 1

Answer:

given

15cot A = 8

cot A = 8/15

squaring both sides

cot²A = 64/225

we know

cosec² - cot²∅ = 1

cosec²∅ - 64/225 = 1

cosec²∅ = 1 + 64/225

cosec²∅ = 289/225

cosec∅ = 17/15

this is correct answer you can believe on this.

hope this will help you
