If you look up that exact equation on google you get -0.952380952 and you just round it to get -0.96
Answer:
G'(3,2)
F'(1,4)
H'(-1,1)
(-y,x)
Step-by-step explanation:
The sum of the measures of angles in the polygon with n angles is
180°(n - 2)
We have an octagon → n = 8.
The sum of the measures of angles in an octagon is
180°(8 - 2) = 180°(6) = 1080°
The equation:
x + 139 + 140 + 125 + 116 + 152 + 2x + 143 = 1080
3x + 815 = 1080 <em>subtract 815 from both sides</em>
3x = 265 <em>divide both sides by 3</em>
<h3>x = 88 1/3</h3>
=
