a = 8

b = ?
c = 17
c2-a2=b2

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.

To find the value of b, we can use the formula:

c^2 - a^2 = b^2

Plugging in the given values, we have:

17^2 - 8^2 = b^2

Calculating the squares:

289 - 64 = b^2

Simplifying:

225 = b^2

To find b, we take the square root of both sides:

sqrt(225) = sqrt(b^2)

Simplifying further:

15 = b

Therefore, b is equal to 15.

To find the value of b, we can rearrange the equation c2 - a2 = b2, and solve for b.

Step 1: Substitute the given values into the equation.
c2 - a2 = b2
17^2 - 8^2 = b2

Step 2: Simplify the equation.
289 - 64 = b2
225 = b2

Step 3: Take the square root of both sides to solve for b.
√225 = √b2
15 = b

Therefore, the value of b is 15.
