Answer:

  C  log3(√((x -4)/x)

Step-by-step explanation:

The applicable rules of logarithms are ...

  log(a/b) = log(a) -log(b)

  log(a^n) = n·log(a)

The base is irrelevant, as long as all logs are to the same base.

__

  \dfrac{1}{2}(\log_3{(x-4)}-\log_3{(x)})=\dfrac{1}{2}\log_3(\dfrac{x-4}{x})=\boxed{\log_3\left(\sqrt{\dfrac{x-4}{x}}\right)}

The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 360 degrees.
serg [7]

Answer: False

Step-by-step explanation:

Triangle is a polygon with 3 sides. The formula for calculating the sum of angle in a polygon is given as :

(n-2)180

where n is the number of sides , so to calculate the sum of angles in a triangle we have :

(3-2) 180

= 1 x 180

= 180

Therefore : The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 180 degrees.
