Step-by-step explanation:
I find area by basically taking the figure and making it into two figures and solving the area for the two then adding them up.
Answer:
The answer is the picture I inserted the way to rewrite it is set-builder notation. Hope this helps :)
Step-by-step explanation:
1- write in set-builder notation
We can simply observe that.
- 0.777... is rational, because it is a number with infinite but repeating decimal part.
- 1/3 is rational, because it's the division between two integers
, so this is rational as well.
Since the product of two rational numbers is always rational, we have that

are all rationals, since they are the product of two rationals.
On the other hand, we have

and thus

which is irrational.
The hypotenuse of the triangle is given by:

Substituting values:

Clearing CB we have:

Then, the perimeter of the triangle is:

Substituting values:
Answer: the perimeter of triangle BRC in units is: D.6 + 2√5
