Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²
We have a=10, b=14 and c=18
a² + b² = 10² + 14² = 100 + 196 = 296
and
c² = 18² = 324
296 < 324 ⇒ obtuse triangle.
All three sides are the same size
100 - 3(3y - 4x) = 100 - 3(18 - 16) = 100 - 3(2) = 100 - 6 = 94
