2 answers:
Answer: B.
Step-by-step explanation:
Given: Time taken by Oliver to complete the project = hours
Since Oliver completed his project in no more than ( ≤ ) twice the amount of time it took Karissa to complete her project.
If k represents the amount of time that it took Karissa to complete her project.
Then , we have the following inequality to represent the situation.

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
