Question

If cosec theta is ✓7 where theta is an acute angle verify sin square theta + cos square theta equal to 1

Answer 1

Answer:

solved

Step-by-step explanation:

let theta = ∝

cosec theta is ✓7

cosec  ∝ =  ✓7 , sin∝ = 1/ ✓7    , cos ∝ = √6/ ✓7

sin square theta + cos square theta  = sin²∝ + cos²∝ = 1/7 + 6/7 = 7/7 = 1
