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.

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
