I need help with number 1-4 I don’t understand..
Karo-lina-s [1.5K]

Answer:

  1. 109°, obtuse
  2. 131°, obtuse
  3. 53°, acute
  4. 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.

Some students can plant 9 carrots per square foot in the community garden shown. Write a function that can be used to determine
Lunna [17]

Answer:

144 carrots

Step-by-step explanation:

Let C stand for the number of carrots that a student can plant.

We are told that carrots may be planted at a density of 9 carrots/ft^2.

Let A be the area, in ft^2, that can be planted with carrots.  The area of a rectangle is Base x Length (in feet).

We can therefore write:

C = (9 carrots/ft^2)*A

In the garden shown, the area is A = (4 ft) x (4 ft) = 16 ft^2

C = 9 carrots/ft^2)*(16 ft^2)

C = 144 carrots
