Answer:
y ≈ 61
Step-by-step explanation:
Using the Sine rule in the triangle
= 
( cross- multiply )
y × sin18° = 21 × sin117° ( divide both sides by sin18° )
y = 
≈ 61 ( to the nearest whole number )
Let A be the number of Adult tickets and S, the Students'
A+ S = 273, but we know that S=2.A
Then A + 2A = 273 ; 3A =273; A =273/3 =91
