Answer: Options 1, 3, 5

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals, so since the slope of the given line is 1/3, we need to find lines with a slope of -3.

  • Option 1 has a slope of -3.
  • Option 2 has a slope of 3.
  • Option 3 has a slope of -3.
  • Option 4 has a slope of 1/3.
  • If we subtract 3x from both sides, we get y=-3x+7, so option 5 has a slope of -3.

I need help with this question on my geometry homework
Margarita [4]

Answer:

x = 250°

Step-by-step explanation:

Inscribed angle = ½(intercepted arc measure) (inscribed angles theorem)

x is intercepted arc measure

125° is the inscribed angle

Therefore:

125° = ½(x)

Multiply both sides by 2

2*125° = x

250 = x

x = 250°
