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
A (2^2/2^-1)is the correct answer because 2^-5 * 2^8 = 8 and 2^2/2^-1 = 8.
Answer:
7.25x+108.75
Step-by-step explanation:
It's just a bit of substitution, you cant get a single whole integer value, because there isn't enough information to solve for a non variable (x) value.
