Answer:
x = 10
Step-by-step explanation:
Perimeter of a triangle = the sum of the three sides.
In an isosceles the legs are equal (2x - 6) and the base is x
Perimeter = (x) + (2x - 6) + (2x - 6)
38 = 5x - 12
38 + 12 = 5x
50 = 5x
10 = x
The measuring unit is the standard unit of a quantity
The measuring unit of size 0.001 is represented by one millionth circle
<h3>How to determine the unit of base 0.001</h3>The basic measuring unit in base 7 is given as:
49 circles
The above can be represented as:
Base 7 = 49 circles
Represent the base with n.
So, we have the following rule
For measuring unit 0.001, we have:
Evaluate the square
This means that,
The measuring unit of size 0.001 is represented by one millionth circle
