60

Step-by-step explanation:

There is a famous pythagorean triplet: 8, 15, 17

8 - leg

15 - leg

17 - hypotenuse

Area of triangle = 1/2base x height

To solve the area of this triangle, you can not use 17.

Base = 8

Height = 15

1/2 of 8 = 4

4*15 = 60

Hope this helps :)

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
