B is the answer hope I help
"x" is the "alternate interior" to the missing angle atop, and a flat-line, is just a line with an angle of 180°, thus, 28 + 103 + x = 180
Answer:
42
Step-by-step explanation:
Given m and n are parallel:
x + 138 = 180 because these angles are supplementary
subtract 138 from both sides
x = 42
Answer:
2 solutions
-1 and 3 is the real solutions
well I know for a fact that the equation for a parabola is

so obviously it is an equation for an ellipse, sadly I am not exactly sure whether the answer is b or c.(I'm leaning towards b)
hopefully I helped out by eliminating 2 options.
Brainliest people comment what the answer is!!!!
Have a great day
