Answer:

  11) C: (a, 4), (b, 3), (c, 2), (d, 1); V: (a, c), (b, d), (4, 2), (3, 1);

     AI: (c, 4), (d, 3); AE: (a, 2), (b, 1); SI: (c, 3), (d, 4); SE: (a, 1), (b, 2)

  12) : C: (a, y), (b, x), (c, w), (d, z); V:(a, c), (b, d), (w, y), (x, z);

     AI: (b, z), (c, y); AE: (a, w), (d, x); SI: (b, y), (c, z); SE: (a, x), (d, w)

Step-by-step explanation:

This is a vocabulary question. It is intended to see if you understand the meaning of the names given to the different angle pairs in this geometry.

All of the pairs of angles filling the first 4 blanks (corresponding, vertical, alt. int., alt. ext.) are congruent pairs of angles. The pairs of angles filling the last two blanks (same-side ...) are supplementary angles (total 180°).

__

<em>Corresponding</em> angles lie in the same direction from the point of intersection. For example, the upper-left angles are corresponding.

<em>Vertical</em> angles are formed from opposite rays.

<em>Alternate</em> refers to angles on opposite sides of the transversal. (<em>Same-side </em>refers to angles on the same side of the transversal. Same-side angles are also called <em>consecutive</em> angles.)

<em>Interior</em> refers to angles that are between the parallel lines. <em>Exterior</em> refers to angles outside the parallel lines.

__

The figures are a bit fuzzy. We assume the angle designations are (CW around the intersection point from upper left, left group first) ...

  Figure 11) {a, b, c, d}, {4, 3, 2, 1}

  Figure 12) {d, c, b, a}, {z, w, x, y}

If this is not correct, you will need to make appropriate substitutions in the pairs given below.

__

11) Corresponding: (a, 4), (b, 3), (c, 2), (d, 1)

  Vertical: (a, c), (b, d), (4, 2), (3, 1)

  Alternate Interior: (c, 4), (d, 3)

  Alternate Exterior: (a, 2), (b, 1)

  Same-side Interior: (c, 3), (d, 4)

  Same-side Exterior: (a, 1), (b, 2)

__

12) Corresponding: (a, y), (b, x), (c, w), (d, z)

  Vertical: (a, c), (b, d), (w, y), (x, z)

  Alternate Interior: (b, z), (c, y)

  Alternate Exterior: (a, w), (d, x)

  Same-side Interior: (b, y), (c, z)

  Same-side Exterior: (a, x), (d, w)

_____

<em>Additional comment</em>

The vocabulary is used to cite various theorems supporting claims regarding angle relationships. In practice, when the lines are parallel, all obtuse angles related to a transversal are congruent, all acute angles are congruent, and the acute angles are supplementary to the obtuse angles. (If the angles are 90°, neither acute nor obtuse, then they are all congruent.)

You need to paint a decorative garden ornament that is in the shape of pyramid with a square base
KATRIN_1 [288]

Step-by-step explanation:

Total Surface area of a pyramid is given as

= Lateral surface area + area of base.

Lateral surface area = 1/2×perimeter of base×slant height

given the base is square with side 9 in , and slant height of 12 inches.

therefore, LSA = 1/2(9*4)×12 = 216 in^2

Now, TSA = LSA + Base area = 216+9^2 = 297 in^2

a) It is given that the pyramid is smaller therefore, it will require lesser paint than the original pyramid ( The TSA of the smaller pyramid cannot be calculated as its dimentions are not given).

b) It can not be solved as dimensions are missing in the question.

However, the logic has been explained in the soluion one easily put values to find the solution.

Im dumb as heck so plez halp​
spayn [35]
The answer is 4
The area is length X width
It is also a square meaning all sides are equal
So with this is mind we can ask the question what times what equals 16 and is the same number
This would be 4 since 4 times 4 is sixteen

Please help I will give out brainliest
Licemer1 [7]

Answer:

Step-by-step explanation:

Our function is : 3x²-3x-1

  • 3x²-3x+2=2
  • 3x²-3x-1+3=2
  • 3x²-3x-1= -1
  • the number that gives us -1 is 1 (from the graph)

so x is 1

  • 3x²-3x-1= x+1  ⇒3x²-4x-2 = 0
  • Δ(the dicriminant)= (-4)²-4*3*(-2)= 16+24 =40
  • two solution x and y
  • x= (4-√40)/6 and y= (4+√40)/6
  • x= -0.38 and y = 1.7
  • so the estimations are -0.38 and 1.7
