400

To solve the equation $(66)^{2} - (34)^{2} + ?^{2} = (60)^{2}$ , we need to find the value of '?'.

- Let's evaluate each square:

- $(66)^{2} = 4356$

- $(34)^{2} = 1156$

- $(60)^{2} = 3600$

- Now plug these values into the equation:

- $4356 - 1156 + ?^{2} = 3600$

- Simplify:

- $3200 + ?^{2} = 3600$

- Rearrange the equation:

- $?^{2} = 400$

- Take the square root of both sides:

- $? = 20$

- Option 3: 20 is the correct answer.
