Please help I need this so I can pass a test

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

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
