b. 0.46
Step-by-step explanation:
i don't know if this right, so lmk
Step-by-step explanation:
we use the law of sine :
sin(A)/a = sin(B)/b = sin(C)/c
with the related angles being opposite of the lines.
so, we have
sin(A)/1 = sin(A) = sin(90)/ sqrt(10) = 1/ sqrt(10) =
= 0.316227766...
cos²(A) + sin²(A) = 1
cos(A) = sqrt(1 - sin²(A)) = sqrt(1 - 0.1)) = sqrt(0.9) =
= 0.948683298...
tan(A) = sin(A)/cos(A) = 0.333333333...
cot(A) = 1/tan(A) = 3
sec(A) = 1/cos(A) = 1.054092553...
csc(A) = 1/sin(A) = 3.16227766...
Answer:
True
Step-by-step explanation:
- If it snows today, I will have to go out and clean the driveway.
- If it does not snow today, I will not have to out and clean the driveway.
- Without going into p's and q's and true false tables, I believe the negation is also true.
You only get brainliest if you answer questions (the person who wrote the question gives out brainliest)
Remember PEMDAS. We start with the parentheses. 2-1=1. Then 1^2 is just one. Now we do (1*5) and (9/3) separate. Now we add them both together 5+3. The final answer is 8
