Answer:
7
Step-by-step explanation:
Use secant-tangent product theorem.
1. Set up the equation
(x-3)(x-3+5) = (x-1)²
2. Solve
(x-3)(x+2) = (x²-2x+1)
(x²-x-6) = (x²-2x+1)
3. Solve for x
Subtract x² from both sides
-x-6 = -2x+1
Add 2x and 6 to both sides
x = 7

Answer: 13
Step-by-step explanation:
Pythagoras's theorem:
A^2 + B^2 = C^2
12^2 + 5^2 = x^2
144 + 25 = x^2
169 = x^2
13 = x
