Question

Find the unknown side of the triangle below.
9 in
18.8 in
15 in
8 in

Answer 1

It’s 9
If you do a^2+b^2=c^2 which basically means 8+x=17, x would add up with 8 to 17. So that’s why it’s 9 :)

Answer 2

its actually 15 inches, cause if you bring the bottom line up and compare it to the 17 line its a smidge shorter so go with the largests number the less then 17. theres proof for the quiz itself
