Can someone help me find AB and BC
Bond [772]

  • 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 person walks 80 feet in 40 seconds. what equation represents this relationship. how many feet will the person walk in 10 secon
larisa [96]

Answer:

20 feet

Step-by-step explanation:

\frac{80 feet}{40 seconds}  = \frac{x feet}{10 seconds}

Simplify \frac{80}{40}

\frac{80}{40} = \frac{2}{1}

Every 1 second, a person will walk 2 feet.

\frac{x}{10} = \frac{20}{10}

X = 20 feet
