Finding the Area of a Regular Polygon The apothem of a regular hexagon measures 8 cm. Which are true of the regular hexagon? Check all that apply. The perimeter of the hexagon is 48 cm. The measure of the angle formed by the radius and the apothem is 30°. The side length of the hexagon is about 4.6 cm. In a regular hexagon, the radius and side length are equal in length. The area of the hexagon is about 221.7 square cm. 8 cm Intro Done
-The measure of the angle formed by the radius and the apothem is 30
- in a regular hexagon, the radius and side length are equal in length.
-the area of the hexagon is about 221.7 square cm.
Answer from: Quest
{x = -1/2 , y = -1
step-by-step explanation:
solve the following system:
{2 x + y = -2
{10 x - 3 y = -2
in the first equation, look to solve for y:
{2 x + y = -2
{10 x - 3 y = -2
subtract 2 x from both sides:
{y = -2 x - 2
{10 x - 3 y = -2
substitute y = -2 x - 2 into the second equation:
{y = -2 x - 2
{10 x - 3 (-2 x - 2) = -2
10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:
{y = -2 x - 2
{16 x + 6 = -2
in the second equation, look to solve for x:
{y = -2 x - 2
{16 x + 6 = -2
subtract 6 from both sides:
{y = -2 x - 2
{16 x = -8
divide both sides by 16:
{y = -2 x - 2
{x = -1/2
substitute x = -1/2 into the first equation:
{y = -1
{x = -1/2
collect results in alphabetical order:
answer: {x = -1/2 , y = -1
