To see if line segments may form a triangle basically one must check if the sum of two sides are greater than the third.
a + b > c
a + c > b
b + c > a
a. can form a triangle
b. can form a triangle
c. can form a triangle
d. cannot form a triangle as 14 + 21 = 35 which is not greater than 36
a = right triangle with the right angle between 16 and 30
b = acute triangle
c = obtuse triangle with teh obtuse angle between 7 and 24

Answer:
Step-by-step explanation:
H = V/ pie r^2
H = 
R= 5 because the radius is half the diameter
Pies cancel out leaving you with:
H = 2200/5^2
H = 2200/25
H = 88

2*1=2
2*2x=4x
-182=4x+2-2
-182=4x
