The value of the missing length is 20
Let the missing length be x
From Parallel lines and transversal theorem, we have that
If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.
Then, we can write that

x = 20
Hence, the value of the missing length is 20

The mean goals scored by the soccer players this season is 18.3 goals
<h3>What is mean? </h3>
Mean is the ratio of the sum of data to the total sample of data.
If three soccer players are scored 25 goals this season., five soccer players scored 19 goals this season and ten soccer players scored 16 goals this season, the mean goal scored is expressed as:
Mean goal scored = 3(25)+5(19)+10(16)/3+5+10
Mean goal scored = 75 + 95+160/18
Mean goal scored = 330/18
- Mean goal scored = 18.3 goals
Hence the mean goals scored by the soccer players this season is 18.3 goals
