Answer:
Therefore elements greater than 5 is only 11.
Step-by-step explanation:
Set:
A set in mathematics is a collection of well defined and distinct objects, also consist of a collection of elements.
Example:
Let A be the set for {-8, 0, 5, 11}
∴ A = {-8, 0, 5, 11}
This is the set ' A 'consists of elements as a number -8, 0, 5, 11.
Therefore elements greater than 5 is only 11. ( 5 will not come as it is mentioned greater than 5 )
-8, 0 are less then 5
Answer: A number plus one doubled
<span>Given cotA + cotB + cotC = sqrt3
to prove triangle ABC is equilateral
we prove this by assuming ABC to be equialteral and establishing the truth
of the statement cotA + cotB + cotC =sqrt3
since ABC is equialteral angleA=angleB=angleC=60 degrees
cotA=cotB=CotC = cot60= 1/sqrt3
therefore cotA + cotB + cotC = 1/sqrt3 + 1/sqrt3 + 1/sqrt3
=3/sqrt3
=sqrt3 which is equal to the RHS ( right hand side) of the expression
hence our assumption that ABC is equilateral is true</span>
