Vertical angles are formed by two lines and are opposite each other
Vertical angles are equal
You would find the sign if the signs are not the same if you are dividing or multiplying its negitve if its the same its positive
A= -81 + square root of 113
a<span>≈</span> -70.36985418
Since 6 is in the hundredths place,
96/100
You can divide that by two for a different, but equal fraction.
48/50, 24/25
24/25 is the simplest form.
I hope this helped you!
