Answer:
R OR E
R'
Step-by-step explanation:
Or is union
And is intersection
' is not
Answer:
-16=-16
Step-by-step explanation:
You would first do (-4-2) which would be (-6), after you would multiply (-6) by 4 which comes out to be -24, after you would add 3 which would look like this -24+3 but since its a negative it would come out to be -21 then you would do the same thing with 5, it would look like this -21 + 5 but since its negative it would be -16. I hope this helped :)
To solve for the missing steps, let's rewrite first the problem.
Given:
In a plane, line m is perpendicular to line t or m⟂t
line n is perpendicular to line t or n⟂t
Required:
Prove that line m and n are parallel lines
Solution:
We know that line t is the transversal of the lines m and n.
With reference to the figure above,
∠ 2 and ∠ 6 are right angles by definition of <u>perpendicular lines</u>. This states that if two lines are perpendicular with each other, they intersect at right angles.
So ∠ 2 ≅ ∠ 6. Since <u>corresponding</u> angles are congruent.
Therefore, line m and line n are parallel lines.
