Answer:
acute
Step-by-step explanation:
Given the 3 sides of a triangle a, b, c ( where c is the longest )
• If a² + b² = c² ⇒ right triangle
• If a² + b² > c² ⇒ acute angled triangle
• If a² + b² < c² ⇒ obtuse angled triangle
Here a = 
, b = 
, c = 4
c² = 4² = 16
a² + b² = ( )² + ( )² = 11 + 7 = 18
Since a² + b² > c² then triangle is acute
