Which of the following sets could be the sides of a right triangle?
a. {2,3, sqrt of 13}
b. {2,2,4}
c. (1,2, sqrt of 3 wouldn't it be b because it has all even numbers?

a. {2,3, sqrt of 13}

Hope this helps, and it's not to late because I know it was 5 years ago lol

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
