2x-8y=-24<br> 6x+4y=68<br> Using elimination method
nikklg [1K]
6(2x-8y=-24)
-2 (6x+4y=68)
12x-48y=-144
-12x-8y=-136
-56y=-280

-280÷-56=5
y=5

2x-8 (5)=-24
2x-40=-24
+40. +40
2x=16
16÷2=8
×=8


y=5
x=8
hope this helps, if needed a picture for better understanding,please comment.

What is the measure of one angle of a regular convex 20-gon
Contact [7]

Answer:

The measure of one angle of a regular convex 20-gon is 162°

Step-by-step explanation:

* Lets explain how to solve the problem

- A convex polygon is a polygon with all the measures of its interior

 angles less than 180°

- In any polygon the number of its angles equal the number of its sides

- A regular polygon is a polygon that is all angles are equal in measure

 and all sides are equal in length

- The rule of the measure of an angle of a regular polygon is

 m=\frac{(n-2)180}{n}, where m is the measure of each interior

 angle in the polygon and n is the numbers of the sides or the angles

 of the polygon

* Lets solve the problem

- The polygon is convex polygon of 20 sides (20 angles)

- The polygon is regular polygon

∵ The number of the sides of the polygon is 20 sides

∴ n = 20

∵ The polygon is regular

∴ All angles are equal in measures

∵ The measure of each angle is m=\frac{(n-2)180}{n}

∴ m=\frac{(20-2)180}{20}

∴ m=\frac{(18)180}{20}

∴ m=\frac{3240}{20}

∴ m = 162

∴ The measure of one angle of a regular convex 20-gon is 162°
