If you want the area, it would be around 166.45
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
Answer:
The radius is 4 because since the diameter is 8, the radius is half of the diameter.
The answer is false 22 isn’t a multiple of 4
The answer is 1/4.
(n+9)/4(n+9)=1/4
