I know the correct answer but I need you to first answer my math questions
B. Collinear
Collinear means that two or more points are on the same line.
Answer:
(c) (-3, 0) and (-5, 0)
Step-by-step explanation:
The given coordinates are -3 -(-5) = 2 units apart on the horizontal line y=-2.
Then the needed coordinates will be on the vertical lines x=-5 and x=-3, and will have y-coordinates that are different from -2 by 2: either -4 or 0.
The points that meet these requirements are (-3, 0) and (-5, 0).
X=3
Explanation:
A straight line equals 180°, and they give you the one angle of 56°, so you know 56+ the other equation has to equal 180
56+4x+112=180
168+4x=180
Subtract 168 from both sides
4x=12
Divide 4 from both sides
X=3
You can check by filling it in.
56+4*3+112=
12+56+112=180
