Question

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

Answer 1

cot a= 8/15

tan a=15/8 [p/b]

using P. T,

p^2+b^2=h^2

225+64=h^2

h^2=289

h=√289= 17.

now, cosec= 1/sin

sin a= p/h= 15/17

=> cosec a= 17/15

Answer 2

Answer:

15/17

Step-by-step explanation:

CotA=8/15 cotA(adjecent/opposite). Ac=Ab+Bc (please put square up of numbers) Ac=225+64 Ac=289=17. CosecA=(hypotenues/opposite). =15/17
