The area of the regular pentagon given a side of 10 in is 172.0 in².
<h3>What is the area?</h3>
A pentagon is an object that is made up of five sides. The sum of the internal angles of a pentagon is 540 degrees.
Area of a pentagon = 1/4√
a²
Where a = side = 10
A = 1/4√ 10²
A = 172.02 in²

Answer:
No, because the first equation equals -1.5x + 2.5 when simplified, but when the second equation is simplified it equals 1
Answer:
{ (1,1),(2,9),(4,8) } is the right answer. Mentioned relation has all the ordered pairs of x and y in the form of set, shown in the table.
Step-by-step explanation:
- Tables can be used to describe functions. i.e. in given table two coordinates x,y used as ordered pairs and their values mentioned, the value x-coordinate comes first and than value of its corresponding y-coordinate .
- According to the table, if we take value of x=1 than we need to take corresponding value of y=1 written as ( 1,1 ), Similarly for if x=2, its corresponding value of 'y' will be y=3 written as ( 2,3 ) and so on
- The entire table expressed in ordered pair gives set { (1,1),(2,9),(4,8) }.
