Answer:y=-1/2

Step-by-step explanation:

125=(1/25)^(y-1)

5^3=(5^(-2))^(y-1)

5^3=5^(-2(y-1))

The same base eliminate each other we then have

3=-2(y-1)

3=-2y+2

Collect like terms

2y=2-3

2y=-1

Divide both sides by 2

2y/2=-1/2

y=-1/2

Please, i need help by tomorrow or I’m going to fail geometry. It’s for 20 points
drek231 [11]

Step-by-step explanation:

the first statement and reason is usually found in what's given at the beginning.

1.a 1. given

the last one is what they want you to prove (also found under what was given)

4. g ( the symbol just means congruent)

supplementary means if I take how far the angle opens up and add it to the other angle I will get a straight line or 180°

the middle letter tells me the corner (vertex) and like opening a book you can see how much the angle opens up. it is a definition for supplementary angles
