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.)

In sentence 7, the phrase by all accounts is best
hram777 [196]

<u>In sentence 7, the </u><u>phrase</u><u> by all accounts is best replaced by </u><u>however.</u>

Correct option is A

  • The sentence that precedes 7 states something that is in contrast with it.
  • Therefore 'by all accounts' in sentence should be changed to 'however' as it is generally used to present something that is different from or contrasts with the previous statement.
  • Thus A is the best answer. The other options are incorrect because they do not convey the contrast that is required in the given context.

What is a phrase in grammar?

  • In syntax and grammar, a phrase is a group of words which act together as a grammatical unit.
  • For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy".
  • Phrases can consist of a single word or a complete sentence.

Kaleb makes an investment at 5.2 percent simple interest. At the end of 1 year, the total value of the investment is $2419.60. H
Dafna11 [192]
The future amount of the current deposit given that the interest is simple and yearly is computed through the equation,
                                 F = P x (1 + in)
where P is the principal amount, F is the future amount, i is the interest (in decimal form) and n is the number of years.

In this certain problem, we substitute the known values to the equation and solve for P,
                             2419.60 = P x (1 + (0.052)(1)) 
                                       P = 2300
Thus, the initial investment was worth $2,300.

You are measuring the height of a statue. You stand 17 feet from the base of the statue. You measure the angle of elevation from
olga_2 [115]

Answer:

height ≈ 31 ft

Step-by-step explanation:

The illustration below will form a right angle triangle. He is standing 17 ft away from the base of the statue.  The angle of elevation from the ground to the top of the statue  is 61°. The height of the statue can be computed below.

adjacent side of the triangle = 17 ft

opposite side = a

Using SOHCAHTOA principle

tan 61° = opposite/adjacent

tan 61° = a/17

cross multiply

a = 17 tan 61°

a = 17 × 1.80404775527

a = 30.6688118396

a ≈ 31 ft
