Answer: z=16
Step-by-step explanation:
Angles on a straight line add up to 180.
As AB is a straight line we can use that to help us find z.
So you would do 68+85+11=164 (I got the 11 from the angle trapped between like C and F as opposite angles are the same).
Then you would do 180-164=16
So z=16
 
Hope this helps :)

Answer:
90 m
Step-by-step explanation:
65 km = 65000m 
1 hour = 3600 secs 
speed in meters = 65000/3600
 = 18 m / sec 
Distance traveled in 5 secs = 18*5
 = 90 m
