By geometry, there is a relationship between the tangent PA and the segments PB and PE, namely
PA^2=PB*PE
so
PE=PA^2/PA=6^2/4=9
BE=PB-PE=9-4=5

Total number of adult tickets = 250
Total number of student tickets = 188
Step-by-step explanation:
Let
a be the number of tickets for adults
and
s be the number of tickets for students
Then
Eqn 1: a+s=438
Eqn 2: s=a-62
Putting s=a-62in eqn 1

Total number of adult tickets = 250
Total number of student tickets = 188
