Answer:

b = 60

Explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² + 63² = 87²

b² + 3969 = 7569 ( subtract 3969 from both sides )

b² = 3600 ( take the square root of both sides )

b =
√(3600) = 60
