Answer 1

Step-by-step explanation:

cosec^2 theta - cot^2 theta = 1

cosec theta - cot theta = k

use identity ( a^2 - b^2 ) = ( a+b )(a-b)

(cosec theta - cot theta)(cosec theta + cot theta)= 1

k(cosec theta + cot theta) = 1

cosec theta + cot theta = 1/k

2. sinA = 1/3 = perpendicular / hypotensue

using Pythagoras theorem

we get base root2

cosA = base / hypotensue = root2/ 3
