Answer:
The base has length 64 m.
Step-by-step explanation:
The area of a triangle = 1/2 * base * height so we have the equation:
256 = 1/2 * b * 8
4b = 256
b = 256/4 = 64 m.
x = 6 ± √30
x² + 2( -6)x + 36 = - 6 + 36
(x - 6)² = 30 ( take the square root of both sides )
x - 6 = ± √30 ( note plus or minus )
add 6 to both sides
x = 6 ± √30 ( exact solutions )
Answer:
4 ft
Step-by-step explanation:
The volume of a cylinder can be written as
V= Bh
where B is the area of the base and h is the height
48pi = 12 pi *h
Divide each side by 12 pi
48pi/12pi = 12pi h /12pi
4 = h
Consider the given parallelogram KLMN.
Prove: 
Statement Reason
1. 
Definition of parallelogram
2. 
Same Side interior angle theorem
3. 
Substitution property
4. 
Subtraction property of equality
Subtraction property of equality tells us that if we subtract some number from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.
5. 
Angle Congruence Postulate
When two angles are equal, then they are said to be congruent by Angle congruence postulate.
Answer:
second
Step-by-step explanation:
No because angles 1 and 2 are same side interior angles but are not supplementary
if the lines were parallel than the same side interior angles 1 and 2 add to 180
60 +115 = 175 so the lines are not parallel
