Only 2 or more 180 degree angles can be considered parallel.
Answer:
8.95
Step-by-step explanation:
here we are going to use pythagoras theorem
a² +b² =c²
the vertical can be taken as a and horizontal as b
4² +8²=c²
this is the same as
c²= 4²+ 8²
c²= 16+ 64
c²=80
to get rid of the square we shall put both sides under a root

c = 8.95

(ii)

Step-by-step explanation:

height of ball (a) = 10m
fraction of height decreases by each bounce (r) = 2/3
