You can find the perimeter of a pentagon by its vertices or by using an unit circle
Answer:
The length between the two points is RT = 1.3 units
Step-by-step explanation:
The coordinates of the point R and T are R(2,1.2) and T(2,2.5).
Now, by DISTANCE FORMULA:
The distance between two coordinates P and Q with coordinate P(a,b) and Q(c,d) is given as:

So, here the distance RT = 
or, RT = 1.3 units
Hence, the length between the two points is RT = 1.3 units
Answer:
19/21 or .90
Step-by-step explanation:
Common denominator.
Multiply 4/7 by 3 which equals to 12/21
Multiply 1/3 by 7 which equals to 7/21
Add 12/21 and 7/21
Answer: 19/21
it is number 1
