Answer:
m = 50
Step-by-step explanation:
∠ D and ∠ A are vertically opposite angles and are congruent , then
m - 130 = 20 - 2m ( add 2m to both sides )
3m - 130 = 20 ( add 130 to both sides )
3m = 150 ( divide both sides by 3 )
m = 50
Answer:
Mathematically speaking, both of these are what are called measures. They are ways of getting at the size of something.
The circumference of a circle is a line, which is one-dimensional, which means it has length but zero width. The area of a circle, in contrast, is two-dimensional. This is the essential difference.
The consequence of this is that circumference is measured in units like centrimetres, or inches, or miles. But area is measured in units like square-centimetres, square inches, or square miles.
Is this what you meant?
