- 3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
- 10x + 20 = 180 [combine like terms]
- 10x = 160 [subtract 20 from both sides]
- x = 16 [divide both sides by 10]
Arc AB measures 3(16) = 48 degrees.
Arc BC measures 2(16) + 5 = 41 degrees.
A. 36 inches is a yard because there are 12 inches in a foot and 3 feet in a yard, so 12 times 3 is 36.
i think answer are big enough
Answer:
You can find the distance between each of the adjacent vertices and then add the results together.
Step-by-step explanation:
Perimeter is all of the side lengths added together, so if you can find the distances between each of the adjacent vertices and then add the together, it will be equivalent to adding all of the side lengths together.
