F (x) = 64(0.5)x
G (x) = 20x+12

Please make me as brain list

Step-by-step explanation:

1. X= 0

2. X=-3/5

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
