Answer: Question # 9: About 17.5 m
Question # 8: 20 m
Explanation:
To find the hypotenuse for both figures you have to "add the squares of the other sides, then after that, take their square root.
For # 9 You would add 9² + 15² = 306, √306 = 17.492... so about 14.5
For # 8 the equation would be 16² + 12² = 400, √400 = 20
