The first graph.
if it is greater then 3 the circle is not filled. if it is greater then OR EQUAL TO 3 then the dot will be filled.
hope this helps!!
Answer: The length of BC ≈ 12.4 cm
Step-by-step explanation:
The first thing we need to do is to find the length of BD which we can solve for with the tangent of 20° which is the opposite side over the adjacent side.
We get tan20° = BD/8.
Solve for BD and you get BD = 8tan20°.
Now we will need to solve for the length of CD which we can get from the tangent of 40°.
We get tan40° = 8/CD
Solve for CD and you get CD = 8/tan40°.
Now that we have the lengths of BD and DC, we can simply add them together to get the length of BC.
(8tan20°) + (8/tan40°) ≈ 12.4 cm
I'm not sure, but I think the answer is B
Since 3/3 and 6/6 are equal to one, you could have many options including 9/9 which is also equal to 1 and 10/10 .
Basically anything over itself could be an answer!
I hope this helps!
