Answer:
and im here for it :D
Step-by-step explanation:
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=32.18, b=40 and c=53.02
a² + b² = 32.18² + 40² = 1035.5524 + 1600 = 2635.5524
and
c² = 53.02² = 2811.1204
2635.5524 < 2811.1204 ⇒ obtuse triangle
