By using the diagram and the given angle measure we get that:
if, m∠1 = 143°
then, m∠2 = 37°
m∠3 = 143°
m∠4 = 37°
What is angles?
An angle is formed when two straight lines or rays meet at a common endpoint.
What is Properties of Congruence?
For all angles A ,
∠A≅∠A .
An angle is congruent to itself.
For any angles A and B ,
if ∠A≅∠B , then ∠B≅∠A .
Order of congruence does not matter.
For any angles A,B, and C ,
if ∠A≅∠B and ∠B≅∠C , then ∠A≅∠C .
If two angles are both congruent to a third angle, then the first two angles are also congruent.
I assume that, this refers to two intersecting lines which form four angles.
- ∠1 and ∠2 are supplementary angles whose sum is 180°.
∠1 + ∠2 = 180°
143° + ∠2 = 180°
∠2 = 180° - 143°
∠2 = 37°.
- ∠1 and ∠3 are vertical angles so do with ∠2 and ∠4.
- Therefore, it is easy to find their measures because vertical angles are congruent in measure.
It means that, ∠1 = ∠3 =143° (properties of congruency)
and ∠2 = ∠4 =37° (properties of congruency).

Answer:
Step-by-step explanation:
1) Check whether the graph is inclusive or exclusive. Inclusive graphs are equal to or greater/less than, whereas exclusive graphs are just greater/less than. A filled circle is inclusive, and a non-filled circle is exclusive. We see that in the graph, the circle is filled meaning it is inclusive. Secondly, we see that the number line goes forever when it is greater than(or equal to) 3. From these two pieces of information, we see that the answer is choice D.
