<h2>Hello!</h2>

The answer is: Dilation with center B and scale factor on A.

<h2>Why?</h2>

Two circles will be always similar because of the ratio proportionality.

Since all circles are similar, we need to prove it by using the following formula:

C_{A} =C_{B}\\C_{A}= 2*\pi *r_{A} =2*\pi *r_{B}\\\frac{r_{B} }{r_{A} } =\frac{9}{3} =3

The number that multiplies Circle A radius to make it similar to Circle B radius is 3.

r_{A}*3=r_{B}=9cm

Have a nice day!

2) 50+50+C = 180
C=180-100 =80
Acute angled triangle

3) 45+45+b =180
b =180-90 = 90 
Right angled triangle

4) 45+60+C = 180
C = 180-105 =75 
Acute angled triangle

5) 94+47+b =180
b = 180-141=39

Obtuse angled triangle

6)81+53+a = 180
a =180-134 = 46

Acute angled triangle

7) 38+45+b =180
b = 180-83 =97
Obtuse angled triangle

8) 36+54+C =180
C =180-90 = 90
