To prove that <span>AEC≅ AED, we need to write following proofs or statement reasons.
It is given that points C and D are equidistant to point A. Hence,
</span><span>AD ≅ AC
Next, </span><span>CAE ≅ DAE. AE is the common side or the included side.
</span><span>
Then, </span><span>AE ≅ EA by Reflexive Property of Congruence as it is congruent to itself.
Lastly, </span><span>EAD ≅ EAC by Symmetric Property of Congruence as these triangles are mirror image of each other.
</span>
Therefore, we can conclude that AEC≅ AED by SSS or Side-Side-Side. That is when all sides of triangles are congruent then both triangles are deemed to be equal.
Answer:
No.
Step-by-step explanation:
The ratio of the lengths of the vertical sides from A to B is 2/4 which equals 1/2.
The ratio of the lengths of the horizontal sides of A to B is 4/11.
Since 4/11 is not equal to 1/2, figure B is not a scale copy of figure A.
Answer:
72π feet
Step-by-step explanation:
circumference of circle= 2πr
Diameter= 2(radius)
radius of circle
= 72 ÷2
= 36 ft
Circumference
= 2(π)(36)
= 72π ft
Answer: 271.
Step-by-step explanation:
When the prior population proportion of success is not available, then the formula to find the sample size is given by :-
Given : Significance level : 
By using the standard normal distribution table ,
Critical value : 
Margin of error : 
Then , the required minimum sample size will be :-
Hence, the required minimum sample size is 271.
