The regular hexagon shown below has a perimeter of 30 and center C. What is the perimeter of triangle ABC.

Option (3)

Step-by-step explanation:

Perimeter of a regular hexagon = 30 units

Length of one side =

                                = 5 units

Interior angle of hexagon =

                                           =

                                           = 120°

BC is an bisector of the angle measuring 120°.

m∠ABC = 60°

Similarly, m∠BCA ≅ ∠CAB ≅ 60°

Therefore, ΔABC is an equilateral triangle.

By the property of equilateral triangle, all sides of the triangle will be equal in measure.

AB ≅ BC ≅ AC ≅ 5 units

Perimeter of triangle ABC = AB + BC + AC

                                           = 5 + 5 + 5

                                           = 15 units

Option (3) will be the answer.

step-by-step explanation:

cats

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
