Answer:
Idk
Step-by-step explanation:
Given:
m(ar LNM) = 280°
To find:
The value of y.
Solution:
Complete angle = 360°
m(ar LNM) + m(ar LM) = 360°
280° + m(ar LM) = 360°
Subtract 280° from both sides.
280° + m(ar LM) - 280° = 360° - 280°
m(ar LM) = 80°
Inscribed angle is equal to the half of the intercepted arc.
The value of y is 40 degrees.

Step-by-step explanation:
Answer: F
Step-by-step explanation:
- This does not have infinitely many solutions (adding the equations, we get a fixed value of x)
- This has no solutions (the left hand sides are the same but the right hand sides have different values)
- This has one solution (the first equation givess a fixed value for x)
- This has no solutions (same reason as 2)
- This has one solution (same reason as 3, just the second equation instead of the first)
- This has infinitely many solutions (multiplying both sides of the top equation by -2 gives the bottom equation).
