x is 14.3

\frac{x}{ \sin(a) } =  \frac{y}{ \sin(b) }

the right angle is 90 degrees, so sin(a) is 90

\frac{x}{ \sin(90) }  =  \frac{9}{ \sin(39) }

multiply sin(90) on both sides to give:

x =  \frac{9}{ \sin(39) }  \times  \sin(90)

x is 14.3

jeyben [28]

Answer:

<u>George fell asleep when he had traveled 1/5 of the total distance, slept 3/5 of the distance and he awoke up when he's still 1/5 away from his grandma</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

George fell asleep a fifth of the way

He awoke up when he still had to travel a quarter of the distance that he had traveled while sleeping

2. For what part of the journey had he been asleep?

George fell asleep a fifth of the way: 1/5 of the total distance traveled and 4/5 of the distance away from his grandma

When he awoke up = 1/4 * 4/5 = 1/5

He had been asleep = 5/5 - 1/5 -1/5 = 3/5

<u>It means George fell asleep when he had traveled 1/5 of the total distance, slept 3/5 of the distance and he awoke up when he's still 1/5 away from his grandma</u>
