Answer:
b. six equilateral triangles
Step-by-step explanation:
The 6 interior angles of the hexagon are supplementary to the exterior angle and are 120 deg. ... Therefore the angles at the center is 360/6 = 60 degrees for each triangle. So all three angles of the six triangles are 60 deg each. So there are 6 equilateral triangles that form the regular hexagon.
Answer: 22
Step-by-step explanation: 44:2=22
8x-12=5x+15

8x=5x+27
subtract 5x from both sides
3x=27
divide by 3
x=9
