Let's call the prices a and c, a for adult...
The cost of an adult ticket is £7 more than the cost of a child ticket:
a = 7 + c
The total cost of the six tickets is £86.
86 = 2a + 4c
c = a-7
86 = 2a + 4(a-7) = 6a - 28
114 = 6a
a = 19
Answer: £19
Check:
That implies c=12.
2a+4c = 2(19)+4(12) = 38 + 48 = 86, good

I will attached the picture of what you are talking about here. The answer for this problem is: Yes, that they are congruent by SAS. Meaning that the triangles are congruent if their included angles and any pair of corresponding sides are equal in both triangles. In this case, the sides are both 21 cm and this will make the angle equal for both triangles, so that is why they are congruent.
