See the attached image to see the alternate interior angles that are congruent (due to the parallel horizontal lines)
tan(angle) = opposite/adjacent
tan(31) = y/400
400*tan(31) = y
y = 400*tan(31)
y = 240.344247611024 <<-- use a calculator; make sure you are in degree mode
y = 240.3
Answer: 240.3
log (m + n) = log m+ log n and proved it m =n/n-1
Given;
If log (m + n) = log m+ log n
To show that the m =n/n-1
Now, According to the question:
We know that,
Log (m + n) = log m + log n
Log (m + n ) = log (mn). [log a + log b = log ab ]
Cancelling the log on both sides.
then,
m + n = mn
=> n = mn - m
=> n = m (n - 1)
=> m = n / n - 1
Hence Proved
log (m + n) = log m+ log n and proved it m =n/n-1
What is Logarithm?
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.

Answer:
Step-by-step explanation:
The answer is C. Hopefully this help. (Less than 14).
Answer:
None.
Step-by-step explanation:
You can write a statement of proportionality without any additional information:
... weight = k × length . . . . . . . . for some constant k
If you need to know the specific weight of a specific length, then you need to know the constant of proportionality (the value of k).
