-5i/2i. is the answer because all you have to do is add the -5 and the i.
0.72 as a fraction is 18/25.
Hoped this helped please mark as brainliest answer please. :)
Perimeter=2L+2W, in this case L=80+2(25) and W=170+2(25) so
P=2(L+W)=2(80+50+170+50)
P=2(350)=700m
<h2>Equations of Circles</h2>
Generally, you'd see the equation of a circle organized in the following format:

is the center
is the radius
To determine the equation given the center and the radius:
- Plug both pieces of information into the general equation
- Simplify
<h2>Solving the Question</h2>
We're given:
- Radius: 99
- Center: (-1,-8)
Plug the radius and center into the equation as r and (h,k):

<h2>Answer</h2>

G=37
Angle ACD and angle DCB are a linear pair. Meaning they are supplementary.
ACD=90 degrees
180-90=90
90 degrees equals the angle of DCB.
90-53=37
So g=37
