Find the measures of the supplement of < A if < A = 2y – 10.

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

Igot the answer of 15.8 years.
