Question

Analyze the diagram below and complete the instructions that follow.

Answer 1

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
