Answer:
B. 5
Step-by-step explanation:
Formula: a^2 + b^2 = c^2
Solution: a is the missing side or x
b is 12 cm
c is 13 cm
x^2 + 12^2 = 13^2
x^2 + 144 = 169
- You need to transpose 144 to the right side so that it will become :
x^2 = 169 - 144
x^2 = 25
- Now you have to discard the square root by using the square root property, it will become:
x = 5
Now the final answer is x = 5
