Answer 2

Answer:

sinA = 40/41. cos A = 9 /41

cotA×cosA = 81/1641

Step-by-step explanation:

cosec2A = 1+ cot2A

(41/40)2. = 1+ cot2A

after solving this

cotA =9/40

cosec A = 1/sinA = 40/41

sinA + cos2A = 1

(40/41)2 + cos2A =1

after solving it

cos A = 9 /41

so

cotA x cos A.

9/40x 9 /41

cotA×cosA = 81/1641
