Answer:
38 cm
Step-by-step explanation:
Circumference is given by
C = pi *d
C = pi *12
C = 3.14 * 12
C=37.68
Rounding to the nearest cm
C = 38

Answer:
Step-by-step explanation:
(x+30) + (x-23) + (2x-7) = 180 degrees
4x = 180
x = 45
m<1 = x+30 = 75 degrees
m<2 = x-23 = 22 degrees
1:2=5:10, hope this helps
