Just add to find X
20 + 60 = 80
-------------------------------------
X = 80
To make sure plug it in
80 - 60 = 20
The equation is true
-----------------------------------------------
x = 80 is your answer
Try the case if the triangle was a right triangle.
Then the longest side, 25, would be c or the hypotenuse.
9^2+24^2=25^2
81+576=625
657=625
This is not a true statement so the triangle is not a right triangle.
Hope this helps :)
Because the number is positive
