Assuming 63 is the side opposite A and 87 is the hypotenuse:
Adjacent = sqrt(87^2 − 63^2) = sqrt(7569 − 3969) = sqrt(3600) = 60.
sin A = opposite/hypotenuse = 63/87 = 21/29.
cos A = adjacent/hypotenuse = 60/87 = 20/29.
tan A = opposite/adjacent = 63/60 = 21/20.
Adjacent = sqrt(87^2 − 63^2) = sqrt(7569 − 3969) = sqrt(3600) = 60.
sin A = opposite/hypotenuse = 63/87 = 21/29.
cos A = adjacent/hypotenuse = 60/87 = 20/29.
tan A = opposite/adjacent = 63/60 = 21/20.
