Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the movie. choose the cost function that represents this scenario if x equals the number of nights laura has the movie

step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
