Answer:
A
Step-by-step explanation:
( ) The null set is always empty.
Solution:
Vertical angles are a pair of opposite angles formed by intersecting lines. re vertical angles. Vertical angles are always congruent.
These two angles (140° and 40°) are Supplementary Angles because they add up to 180°:
Notice that together they make a straight angle.
Hence,
From the image
The following pairs form vertical angles
Hence,
One pair of the vertical angles is ∠1 and ∠3
Part B:
Two angles are said to be supplementary when they ad together to give 180°
Hence,
From the image,
The following pairs are supplementary angles
Hence,
One pair of supplementary angles is ∠5 and ∠6
Answer:
March he sells 51. April he sells 107
Step-by-step explanation:
In jan he made 14 so we double that for feb and have 28.
From that 28 he takes home 5 so we are left with 23.
Then we double 28 for March to get 56 but he takes 5 home which leaves 51 to be sold and so on.
Answer:
- B) Symmetric property of congruence
Step-by-step explanation:
The angles 1 and 2 are marked as congruent
<u>If a ≅ b, then b ≅ a, this is called the symmetric property of congruence:</u>
- The symmetric property states that if one figure is congruent to another, then the second figure is also congruent to the first.
Correct choice is B
