Find 
The sum
a point is 
So:

Angle a is at right angled.
So:

Collect like terms


To solve this, we combine like terms. Our equation becomes:
-2u + 13 = -5
Now to subtract both sides by 13 to find that:
-2u = -18
Finally, we divide both sides by the coefficient and find that:
u = 9
Hello,
Let's be x the length of the 3 side (9,x,23) ==>x>0
Using inequality triangular:
9<x+23==>x>9-23==>x>-14 (done)
x<9+23==>x<32
23<x+9==>x>14
SO 14<x<32
