Answer:

x = 107

Step-by-step explanation:

The sum of the exterior angles of a polygon is 360

105 + 148 +x =360

Combine like terms

253 +x = 360

Subtract 253 from each side

253-253+x = 360-253

x = 107

\begin{cases}

(3R_2)^2+ R_2^2=12 \\ \\ 
9R_2^2 + R_2^2=12 \\ \\ 
10R_2^2=12\\\\
R_2^2 = \frac{12}{10} = \frac{6}{5} \\ \\ 
R_2 = \boxed{\sqrt{\frac{6}{5}} } \\ \\ 
R_1 = \boxed{3\sqrt{\frac{6}{5}} }$
