Answer:
1 and 4 because it has 4 sides
In general, any equation like (assuming ) is solved by
So, in your case, the solution is
Dividing by a fraction means to multiply by the inverse of that fraction:
hypotenuse = 14 = c
short leg= 8 = b
long leg = ? = a
Formula
c^2 = a^2 + b^2
Substitution
14^2 = a^2 + 8^2
Simplification
196 = a^2 = 64
a^2 = 196 - 64
a^2 = 132
Result
a = 11.5
