Answer:
i. <DCB = 
ii. Sin of <DCB = 0.8
Step-by-step explanation:
Let <DCB be represented by θ, so that;
Sin θ = 
Thus from the given diagram, we have;
Sin θ = 
= 0.8
This implies that,
θ =
0.8
= 53.1301
θ = 
Therefore, <DCB =
.
So that,
Sin of <DCB = Sin 
= 0.8
Sin of <DCB = 0.8
Domain: {1,2,3,5,7}
Range: {4,9,7,12}
Step by step, we have:
1 • (-1)= -1
Then -1 • 1 = -1 and -1 • (-1)= 1 =》 1 - 1 = 0
The answers is 0
