If a^2+b^2=c^2 then it's a right angle
If a^2+b^2>c^2 then it's acute
If a^2+b^2< c^2 then it's obtuse. 3.1^2+3^2. 5^2
1+9. < 25
#3 is obtuse
4. 28^2+45^2. 53^2
2809. 2809
#4 is a right triangle
5. 9^2+11^2. 13^2
81+ 121 =202.> 169
#5 is acute

<em>I'm not %100 percent certain because I learned that a long time ago.</em>
Answer: -4x+5>-5=x>2.5
-25>-5(x+2.5)=x<2.5
Step-by-step explanation:
-4x+5>-5 -25>-5(x+2.5)
-5 -5 -25>-5x-12.5
-4x>-10 +12.5 +12.5
/-4 /-4 -12.5>-5x
x>2.5 /-5 /-5
2.5>x
x<2.5
Answer:
