At a charity fund-raiser, adult tickets were sold for $11 each and children's tickets were sold for $2 each. Write an algebraic expression for the total amount of money raised from the sale of tickets. How much money was raised from the sale of tickets. How much money was raised if the fundraiser sold 249 adult tickets and 388 children’s tickets? Let a= the number of adults tickets and let c= the number of child tickets. Then, an algebraic expression for the total money raised from sale of tickets is

The answer to this is 47.5 degrees.

Step-by-step explanation:

To find the missing angle of a triangle, you must first understand what the known angles are. For this triangle you have 2 angles already known, the 42.5 degree angle, and the 90 degree angle. An angle will always be 90 degrees if it has that little square. When a triangle has a single 90 degree angle, that triangle will be a right triangle. the following angles will add up to 90 degrees, and so you can just take 90 and subtract 42.5 from it, to find the missing angle length of 47.5 degrees.
