Consecutive intergers are 1 away from each other so
numbers are
x,x+1,x+2
average is found by adding the numbers up and dividng the total by the number of numbers you have
so we add x+x+1+x+2 up and divide it by 3 (3 numbers)
x+x+1+x+2=x+x+x+1+2=3x+3
(3x+3)/3=53
[3(1x+1)]/3=53
3/3 times 1x+1=52
1x+1=53
subtract 1 from both sides
x=52
subsitute
x+1 is the second
x+2 is the third
x+1=52+1=53
x+2=52+2=54
numbers are 52,53,54
Answer:
<h2>440 square units</h2>
Step-by-step explanation:
We can find half of a side of the pentagon with the expression
Because, as a regular polygon, all its sectors have the same central angle, and the apothem divides equally each sector in two equal parts.
Therefore, half of a side is 8 units long, which means each side measures 16 units.
Now, the area of a penthagon is defined by
Where 
is the perimeter and 
is the apothem. Where the perimeter is the sum of all sides, which is 80 units.
Therefore, the right answer is the second choice.

2(i).
(3y-20)+(4x-5)+(x+y-10)+(2x+5)=360 (Angles sum of it trapezium)
3y-20+4x-5+x+y-10+2x+5=360
7x+4y=390

2(ii).
(3y-20)+(2x+5)=180 (Interior Angles, Parallel Lines)
2x+3y=195
