I decided to do a addition problem because based on the answer it couldn't be multiplication, subtraction, or division. Therefore, my problem would look like 15+9=24 birds in total.
Answer:
a^2 - 25
Step-by-step explanation:
5(a-5) turns into 5a - 25
a(a-5) turns into a^2 - 5a
added together, it's a^2 - 25
If it involves an Arc, the inscribed angle is 1/2 of the measure of the are across from it. If the figure inscribed in a quadrilateral, opposite angles are supplementary (when added together equals 180 degrees) This is all I know :)
