Question

Sin∅=24/25, find the cos

Answer 1

Step-by-step explanation:

sin A = 24 / 25

as we know that :

sin ² A + cos ²A = 1

cos ²A = 1 - sin²A

cos ²A = 1 - ( 24/25) ²

cos² A = 1 - 576 / 625

cos ²A =. 625 - 576 / 625

cos ² A. =. 49 / 625

cos A =. √ 49/ 625

cos A = 7 / 25

plz mark my answer as brainlist plzzz .

I hope you will find it useful .

plz it took a really great effort .

Answer 2

Answer:

θ=2πn1  + arcsin(24/25), n1  ∈ Z or θ=2πn2 +π−arcsin(24/25) , n2  ∈ Z
