Question

If sin A =to 24/25 then the value of cos A is

Answer 1

Step-by-step explanation:

Given that:-

Sin A = 24/25

squaring on both sides,then

Sin^2 A = (24/25)^2

=>Sin^2 A = 576/625

=> 1-Sin^2 A = 1-(576/625)

=>Cos^2 A = (625-576)/625

=>Cos^2 A = 49/625

=>Cos A = √(49/625)

=>Cos A = 7/25

Used formula:-

Sin^2 A+ Cos^2 A =1
