Answer:
x = 10
y = 40
Step-by-step explanation:
DE is a straight line so the sum of angles DBA and ABE is equal to 180
13x - 18 + 5x + 18 = 180 add like terms
18x = 180 divide both sides by 18
x = 10
Same rule applies when calculating value of y
3y - 52 + 2y + 32 = 180 add like terms
5y - 20 = 180 add 20 to both sides
5y = 200 divide both sides by 5
y = 40
A polygon with 7 sides is a heptagon.
Given:
number of sides = n = 7
The sum of interior angles in a polygon is given by;
Therefore, the sum of the interior angles of a polygon with 7 sides is 900 degrees.
Angie has a total of 6.5 yards of ribbon. Her goal is to take advantage over it by making a wreath. Each wreath has length of 1 1/3 yards.
In order for us to know how many wreath will be made, we'll divide the fraction to the total length of the ribbon.
= 6.5 / 1 1/3
= 6 1/2 / 4/3
= 13/2 * 3/4
= 39 / 8
= 4.875
So, there are 4 bows or wreath can be made.

I’m not positive, but I think the answer is C because when you look at the big triangle, it looks like you divide each coordinate by 3 (or multiply it by 1/3) to get the small triangle.
e.g. 6 * 1/3 = 2, 3 * 1/3 = 1
