What type of triangle has side lengths 2, √11, and √15? leave details as to how you got to your conclusion im confused

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=2, b=√11 and c=√15

2² + (√11)² = 4 + 11 = 15
and
(√15)² = 15

15 = 15   ⇒  right triangle.

Hope this helps.

Ithink it is15not sure tho

__tx= 60 inches. __cause it's equal to vt
