Answer:
r = 
Step-by-step explanation:
The common ratio r is calculated as
r =
=
=
= 
M8 =43.
Reason:
134+ M8 =180(degrees). This is because angles on a straight line =180 (degrees)
180-134=M8
Therefore:
M<8 =180-134= 43 (degrees)
Hope this helps and makes sense.

The formula for an area of a circle is A= pi(r)^2
so if you plug in 5 to r (because it’s the radius) you should get A= 78.5
