Answer:
∠2 = 18°
Step-by-step explanation:
∠WXZ = ∠1 + ∠2 ← substitute ∠1 = 3∠2
∠WXZ = 3∠2 + ∠2, that is
72 = 4∠2 ( divide both sides by 4 )
18 = ∠2, that is
∠2 = 18°

Answer:
9.52% ( to 2 dec. places )
Step-by-step explanation:
Calculate the percentage increase using
percent increase =  × 100%
 × 100%
increase = 46 - 42 = 4, hence
percent increase =  × 100% ≠ 9.52%
 × 100% ≠ 9.52%
 
        
             
        
        
        
You find the circumference of a full circle so 2πr =43.98
then divide by 4=10.995
so the answer is 10.995cm
