Question

State of the three sides form an acute,obtuse or right triangle :17,21,28 are the sides

Answer 1

Solution

For this case we have the following 3 sides given: 17.,21 and 28

We can assume that a= 17, b = 21 and c= 28

And we have this condition:

[tex]c^2Then the triangle needs to be : Acute

the final answer is:

The triangle is Acute because the longest side squared is 784 which is lower the sum of squares of the other two sides which is 730
