Answer:

x = 3; y = 6; z =4

Step-by-step explanation:

The point J is the circumcentre of the triangle.

It is equidistant from the vertices. So

2x + 2 = 8

2x = 6

x = 3

2y - 4 = 8

2y = 12

y = 6

If FI = 9, HI = 9. Then,

3z - 3 = 9

3z = 12

z = 4

So, x = 3; y = 6; z =4.

Question

Ahat [919]

Answer:

4 minutes.

Step-by-step explanation:

There are three trains that Rachel has to take to go to her job. The total time is taken by her, on average, 1 hour and 20 minutes i.e. (60 + 20) = 80 minutes.

In his journey, she walks for 15 minutes and a train journey for about 53 minutes.

Then the total waiting time for the trains is (80 - 53 - 15) = 12 minutes.

Therefore, the average waiting time, in minutes, at each of the three train stations will be $\frac{12}{3} = 4$ minutes. (Answer)
