Answer:
3(x32+12)
Step-by-step explanation:
Speed times time=distance
distance=6.8
speed=2.72
time=?
2.72 times ?=6.8
divide both sides by 2.72
?=2.5
answer si 2.5 hours
Answer:



Step-by-step explanation:
Step 1: Pythagoras Theorem
Pythagoras theorem relates the three sides of the triangle in such a way that the sum of the square of base and perpendicular is equal to hypotenuse, such as:

Step 2: Trigonometric Functions
Only for a right angle triangle following three trigonometric relations are valid



Step 3: Verifying all the possible answers
A: Since, LN = x and using 
we can calculate


therefore, NM = x (true)
B: As NM = x therefore it can not be equal to
.
C: Using Pythagoras Theorem



It can also be proved using trigonometric relation


As, 
Therefore

D and E:
Using same approach similar to part A
Since, LN = x and NM = x
we can calculate


Therefore,
and not equal to 
Tara was right terrence was close but he put the(.) in the wrong spot the correct answer is 243.984 but terrence put 2439.84
