Determine if these sides form a triangle

4√5 = 8.94

√145 = 12.04

So

8.94 + 12.04 > 19

8.94 + 19 > 12.04

12.04 + 19 > 8.94

These sides can form a triangle

Now you need to see what kind of triangle

a^2 = (4√5)^2 = 16 x 5 = 80

b^2 = (√145)^2 = 145

c^2 = (19)^2 = 361

If

c^2 < a^2 + b^2 = acute

c^2 > a^2 + b^2 = obtuse

c^2 = a^2 + b^2 = right

In this case c^2 = 361 > a^2 + b^2 = 80 + 145 = 225

So it's an obtuse triangle
