Gabby walks 8/9 miles to the store. How far has she walked when she has covered 3/4 of the distance to the store?

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

step-by-step explanation:

you can use a^2+ b^2=c^2
