Assuming 87 is the hypotenuse and 63 is the side opposite angle A, the other leg is
sqrt(87^2 − 63^2) = sqrt(7569 − 3969) = sqrt(3600) = 60.
Then
- sin A = opposite/hypotenuse = 63/87 = 21/29,
- cos A = adjacent/hypotenuse = 60/87 = 20/29,
- tan A = opposite/adjacent = 63/60 = 21/20.
sqrt(87^2 − 63^2) = sqrt(7569 − 3969) = sqrt(3600) = 60.
Then
- sin A = opposite/hypotenuse = 63/87 = 21/29,
- cos A = adjacent/hypotenuse = 60/87 = 20/29,
- tan A = opposite/adjacent = 63/60 = 21/20.
