Answer:

The answer is tan²Ф + 1 = sec²Ф

Step-by-step explanation:

∴ sin²Ф/cos²Ф + cos²Ф/cos²Ф = 1/cos²Ф

∵ sin²Ф/cos²Ф = tan²Ф

∵ 1/cos²Ф = sec²Ф

∴ tan²Ф + 1 = sec²Ф

jenyasd209 [6]
Assigning "a" as cost of adult tickets and "c" the cost of children's tickets.

3a + 4c = 107
2a + 3c = 76

elimination method
2(3a + 4c = 107)
-3(2a + 3c = 76)

6a + 8c = 214
-6a - 9c = -228
----------------------
0 - c = - 14
c = 14

Then 2a + 3(14) = 76
2a = 76 - 42
2a = 34
a = 34/2
a = 17
