To find the percentage divide 10 by 100.. each chapter would make up 10% of the book.
F(1)=18
f(2)=18-2=16
f(3)=16-2=14
f(4)=14-2=12
f(5)=12-2=10
Answer:
Can you please attach a picture of the question so I can help?
Step-by-step explanation:
(i just changed my answer)
sqrt is the square root of
v=sqrt(2(ke)/m)
Given that ∠B ≅ ∠C.
to prove that the sides AB = AC
This can be done by the method of contradiction.
If possible let AB
=AC
Then either AB>AC or AB<AC
Case i: If AB>AC, then by triangle axiom, Angle C > angle B.
But since angle C = angle B, we get AB cannot be greater than AC
Case ii: If AB<AC, then by triangle axiom, Angle C < angle B.
But since angle C = angle B, we get AB cannot be less than AC
Conclusion:
Since AB cannot be greater than AC nor less than AC, we have only one possibility. that is AB =AC
Hence if angle B = angle C it follows that
AB = AC, and AB ≅ AC.
