Answer:
No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.
Step-by-step explanation:
Data provided in the question
m∠ABC = 45°
m∠ECD = 45°
Based on the above information, the ΔBAC ~ ΔEDC could be determined by seeing the given options
As we can see that from the last option the AA could not be postulated as it creates a reflection over the line plus the ∠ABC and ∠DEC is not congruent
Therefore the last option is correct
Answer:
,
, 
Step-by-step explanation:
In this problem we have that

we have



substitute the values and solve for x

Group terms that contain the same variable in the right sides

Combine like terms in the right side




<u><em>Find the value of bd</em></u>

Find the value of bc

<u><em>Find the value of cd</em></u>

This is annoying
the perimiter is 34 units
the width is 6.5 units
ok.
perimiter=2(Length+Width)
P=2(L+W)
solve for L
distribute
P=2L+2W
minus 2W
P-2W=2L
divide by 2

given that P=34 units and W=6.5 units

the equation would be

or
Steps:
1: Use the formula V=πr2h
3 to calculate the volume for Right circular cone
2: H is the height, R is the Radius
3: Use 17.7 to calculate the Height.
4: Use 18.2 to calculate the Radius
Description:
Radius: 18.2
Height: 17.7
Shape: Right circular cone
Solved for volume
Formula: V=πr2h
3
Answer: V≈6139.66
