If you meant what I asked above, then your answer is -44. If you add negative numbers, they go down instead of up or they basically became the opposite of positive if that makes sense.
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
Answer:
0
Step-by-step explanation:
if all the points lie on the same line then they have the same slope
Answer:
It would take them 64 hours. However, this is only true if they decrease by two in the end. The question is not very specific.
