<h3>How to identify if a triangle is acute?</h3>
Let us have:
H = biggest side of the triangle
And let we get A and B as rest of the two sides.
Then we get:
If

then the triangle is acute
Two sides of an acute triangle measure as 5 inches and 8 inches
The length of the longest side is unknown.
We have to find the length of the unknown side
WE know that the longest side of any triangle is a hypotenuse
For an acute triangle we know:

Here in this sum,
a = 5 inches
b = 8 inches
c = ?
Substituting we get,

c < 9
Hence, The greatest whole possible whole number length of the unknown side is 9 inches.
