Step-by-step explanation:
Given,
∠CBE ≅ ∠DBE ----> 1
∠CBE ≅ ∠BCA ----> 2
From 1 & 2,
∠BCA≅ ∠DBE ----> 3
∠DBE ≅ ∠BAC ----> 4
Reason,
Since BE II AC, corresponding angles are equal.
From 3 & 4,
∠BCA ≅ ∠BAC
BC is opposite to ∠BCA
AB is opposite to ∠ABC
Side opposite to congruent angles are always congruent.
Therefore,
AB ≅ BC
Hence proved.
Since one angle is 90° and other is 45° ...so by angle sum property the third angle is also 45° ..
There is a theorem which states equal angles in a triangle have their opposite sides equal...hence base is also 6 ...then by Pythagoras Theorem..... x=√72=6√2
Answer:
The more effective way for this data set is the mean.
Step-by-step explanation:
The median required arranging the numbers in an descending-to-ascending order, and it is also preferred if the quantity of the numbers to be an odd number.
In this case, we have repeated numbers, and the quantity is even, which makes finding the median difficult.
