Answer:
Supplementary angles
x = 31
Step-by-step explanation:
Since, (3x + 25)° and 2x° are straight line angles. Therefore they are supplementary angles
(3x + 25)° + 2x° =180°
(5x + 25)° = 180°
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 155/5
x = 31
Let 'x' represent the monthly membership fee for the gyp.
Since 1 year = 12 month for 1 year Alyson will pay 12x dollars.
But if she pay in advance 12x dollars she will receive $50 discount and pay $514:
12x - 50 = 514
x = $47
The monthly membership fee is $47.
hope it helps
