If you divide 156 by 12 it'll give you 13, so there are 13 in each group
Image of A (2-8, 6+4) =(-6,10)
image of B (-1-8, 5+4)=(-9,9)
Answer:
- 109°, obtuse
- 131°, obtuse
- 53°, acute
- 124°, obtuse
Step-by-step explanation:
You are exected to know the relationships of angles created where a transversal crosses parallel lines.
- Corresponding angles are equal (congruent).
- Adjacent angles are supplementary, as are any linear pair.
- Opposite interior (or exterior) angles are equal (congruent).
The appearance of the diagram often gives you a clue.
You also expected to know the name (or category) of angles less than, equal to, or greater than 90°. Respectively, these are <em>acute</em>, <em>right</em>, and <em>obtuse</em> angles.
1. Adjacent angles are supplementary. The supplement of the given angle is 109°, so x will be obtuse.
2. Opposite exterior angles are equal, so y will be 131°. It is obtuse.
3. Opposite interior angles are equal, so w will be 53°. It is acute.
4. Corresponding angles are equal, so x will be 124°. It is obtuse.
Answer:
A
Step-by-step explanation:
note that these are the factors of a difference of squares
• a² - b² = (a + b)(a - b), hence
(x + 13)(x - 13)= x² - 13² = x² - 169 → A
That's a true statement, simply because ... I believe ...
that's the definition of "similar" figures.
