<em><u>Answer:</u></em>
The answer is 70 degrees.
<em><u>Step-by-step explanation:</u></em>
1. All the angles in a circle add up to 360, and the red square thing in the TVU angle means it's a 90 degree angle.
2. Add 150 plus 50 plus 90 = 290
3. 360 degrees (total) - 290 degrees = 70 degrees! :)
For this case we have the following functions:

We have to:
is given by:

Thus, the correct option is the option is A.
On the other hand,

Thus, the correct option is the option is A.
We also have:

Thus, the correct option is the option is B.
Last we have:

Thus, the correct option is the option is C.
ANswer:
Option A, A, B, C
To find the answer,we can solve this by settin up an equation.
Let x be the number of adult tickets sold.
The number of students ticket sold would be:
x-74
We can then sum them up to set an equation:
x+x-74 = 676
2x = 676 + 74
x = 375
Therefore the adult tickets sold were 375.
