Suppose that a roof is built so that the angle at the peak and the lengths of the sides, which differ, are known. how would the width of the house be determined?

using the Law of Cosines

Step-by-step explanation:

As with many math problems, there are a number of ways this problem can be worked. Perhaps the most straightforward is to use the Law of Cosines to compute the side (c) opposite the given angle (C), given the sides (a, b) adjacent to that angle.

c² = a² + b² -2ab·cos(C)

Then the desired width of the house is ...

c = √(c²)

answer: it's d

step-by-step explanation:

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
