a = 8

b = ?
c = 17
c2-a2=b2

1 answer

To find the value of b, we can rearrange the equation c^2 - a^2 = b^2.

Given that c = 17 and a = 8, we can substitute these values into the equation:

17^2 - 8^2 = b^2

289 - 64 = b^2

225 = b^2

Taking the square root of both sides, we get:

b = ±15

Therefore, b can be either 15 or -15.
