Question

Could someone please tell me the answer

Answer 1

Answer: 12.0

Step-by-step explanation: We need to find the length of one of the leg piece, so this is how we will set up our equation (x is the missing side length):

1. $x^{2}$ + $5^{2}$ = $13^{2}$ (Simplify the square roots)

2. $x^{2}$ +25 = 169 (Subtract 25 from 169)

3. $x^{2}$ = 144 (Take the square root of both sides)

4. x = 12 or 12.0.
