Answer:

  BC= 14.6

Step-by-step explanation:

The law of cosines tells you ...

  BC² = AB² +AC² -2·AB·AC·cos(A)

  BC² = 9² +12² -2·9·12·cos(87°) ≈ 213.695

  BC ≈√213.695 ≈ 14.6

The length of BC is about 14.6 units.

Which choice most effectively combines the
shepuryov [24]

The subject-verb agreement: "Writing as" effectively combines the sentences at the underlined portion.

<h3>What is a Subject-Verb Agreement?</h3>
  • The grammatical principle of the subject-verb agreement states that a sentence's subject and primary verb must agree.
  • Particularly, singular subjects use singular verbs, whereas plural subjects use plural verbs.
  • There must be an agreement between the number of subjects and verbs (singular or plural).
  • This means that if a subject is singular, then the verb must likewise be singular, and if a subject is a plural, then the verb must also be numerous. verbs DO NOT include "an, s" in their single forms.

Therefore option (A) is the correct answer.

What is the value of n?<br> 9×27+2×31-28=n
Elis [28]
Lets use bedmas/pemdas, and simplify the equation to find n.

n = 9 * 27 + 2 * 31 - 28
n = 243 + 2 * 31 - 28
n = 243 + 62 - 28
n = 305 - 28
n = 277

Therefore n = 277.
