Answer:
#1 is 17 and #2 is 25.
Explanation:
You're going to use the Pythagorean Theorem which is a²+b²=c².
1.) a and b are called legs and the missing length is called the hypotenuse. The legs are the numbers given to you, such as, 8 and 15. Plug them into the equation: 8²+15²=c².
2.) 64+225=c²
3.) 289=c²
4.) 25=c
