Answer:
-256
Step-by-step explanation:
<span>On the one hand we know that sin(30) = 1/2. On the other hand we know that sin(A) = a/c. From these two relations we obtain that 1/2 = a/c <=> 1/2 = a/12 <=> a = 12*1/2 <=> a = 6. So the answer is D. 6cm.</span>

Answer: 3:8
Explanation: To get this you have to divide each number by the two numbers' GCF (Greatest Common Factor) and in this case the GCF is 10, so you divide both numbers by 10 and get 3 and 8.
Answer:
H
Step-by-step explanation:
The parallel line BC divides the sides AD and AE in proportion, that is
= 
, that is
= 
( cross- multiply )
3AC = 8 ( divide both sides by 3 )
AC = 
= 2 , hence
AE = AC + CE
= 2 + 4 = 6 → H
