Answer 2

Hey !

Here is your answer !!

________________


Given !

sin A = 24 / 25

As we know that Sin A = Perpendicular / Hypotenuse

Here !

➡Perpendicular = 24

➡Hypotenuse = 25


Now using Pythagoras theorem !!


[25]^2 = (base)^2 + [ 24 ]^2

625 - 576 = ( base )^2

base = √49 = 7

Hence cos A = Base / Hypotenuse = 7 / 25


Hope it helps !!
