Answer:
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
Let student tickets are x and adult tickets are y
x + y = 516.........x = 516 - y .........(substitute in 2)
3x + 5y = 2046 ......(2)
3(516-y) + 5y = 2046
1548 - 3y + 5y = 2046
2y = 498
y = 249
x = 516 - y = 516 - 249 = 267
so the correct answer is b
