W is a right angle, so we have a right triangle with legs 9 and 12, which are three times 3 and 4, so a 3/4/5 right triangle, so the answer is three times 5,

Answer: 15

Answer:

15 units

Step-by-step explanation:

Pythagoras Theorem to be used,

1. a² + b² = c²

2. 9² + 12² = c²

3. 225 = c²

4. √225 = √c²

5. 15 = c
