When you have an equation that has variables and you know the value of those variables, just plug it it. So plugging the vaules we get
Just evaluating we get 4
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
I think yes due to root 2 maybe I am wrong sorry id this was not helpful
Answer:
280,000
Step-by-step explanation:
10^5=100,000
2.8 x 100,000=280,000
0.0065 is how you say sixty-five ten thousandths
