Answer:
∠BKM= ∠ABK
Therefore AB ║KM (∵ ∠BKM= ∠ABK and lies between AB and KM and BK is the transversal line)
m∠MBK ≅ m∠BKM (Angles opposite to equal side of ΔBMK are equal)
Step-by-step explanation:
Given: BK is an angle bisector of Δ ABC. and line KM intersect BC such that, BM = MK
TO prove: KM ║AB
Now, As given in figure 1,
In Δ ABC, ∠ABK = ∠KBC (∵ BK is angle bisector)
Now in Δ BMK, ∠MBK = ∠BKM (∵ BM = MK and angles opposite to equal sides of a triangle are equal.)
Now ∵ ∠MBK = ∠BKM
and ∠ABK = ∠KBM
∴ ∠BKM= ∠ABK
Therefore AB ║KM (∵ ∠BKM= ∠ABK and BK is the transversal line)
Hence proved.
The next number in the sequence will be 12.
<em><u>Explanation</u></em>
The given sequence is: 8, 15, 14, 9, 1, 6, 3
If we express these numbers in words, then we can see that the words are in alphabetical order, like....
Eight, Fifteen, Fourteen, Nine, One, Six, Three
There are two numbers 10 and 12 in the options which starts with letter 'T' , but alphabetically '<u>Tw</u>elve' will be the next number after '<u>Th</u>ree'
So, the next number in the sequence will be 12.
Answer:
cm.
Step-by-step explanation:
We have been given that the average human body cell is about
cm in diameter. The diameter of a plant cell is
cm.
To find the combined diameter of the body cell and plant cell, we will add both diameters.
First of all let us convert our given diameters in standard notation.




Let us convert our answer in scientific notation.

Therefore, the combined diameter of the body cell and plant cell is
cm.
