A=?
17 1/4
16
Using the pythagorean’s theorem.

Step-by-step explanation:

Pythagorean theorem is expressed as

Hypotenuse² = opposite side² + adjacent side²

From the given right angle triangle,

Hypotenuse = 17 1/ inches. Converting to decimal, it becomes 17.25 inches

Adjacent side = 16 inches

Therefore .15.5

17.5² = 16.5² + a²

306.25 = 272.25 + a²

a² = 306.25 - 272.25

a = 34

Taking square root of both sides of the equation, it becomes

a = √34

a = 5.83 inches

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.
