Answer:
Step-by-step explanation:
ΔVWX is an isosceles triangle.
∠V ≅∠W = 20
20 + 20 + ∠X = 180
∠X = 180 - 40
∠x = 140
In ΔPQR
∠P + 20 + 80 = 180 {Angle sum property of triangle}
∠P + 100 = 180
∠P = 180 - 100
∠P = 80
In ΔSTV is an isosceles triangle.
∠S ≅ ∠T = 80°
∠V + 80 + 80 = 180
∠V + 160 = 180
∠V = 180 - 160
∠V = 20°
In ΔPRQ & ΔSTV
∠P ≅ ∠S = 80°
∠R ≅ ∠T = 80°
∠Q ≅ ∠v = 20°
ΔPRQ ` ΔSTV are similar by AAA congruent
bearing in mind that lines with an undefined slopes are vertical lines, Check the picture below.
16 x w x 8 = 1664

Answer:
Step-by-step explanation:
Total: 318
Student tickets: x
Adult tickets: 3x+6
x+(3x+6)=318 -> 4x+6=318 -> 4x=312 -> x=78
3(78)+6 = 234+6 = 240
240 adult tickets were sold
