Answer:
The number of possible values of n is 393.
Step-by-step explanation:
Given ABC is a triangle.
Length of AB = log 8
Length of BC = log 50 and
Length of AC = log n
According to the inequality theorem of triangle, the sum of any two sides of a triangle must be greater than the third side.
Applying the condition,
Using the logarithmic rule, , we get
Applying the same rule to the other combination of sides,
Since n is an integer, therefore
From, 400 > n and n > 7,
we have the number of possible values of n = 400 - 7 = 393
Hence, n can take 393 possible values.
