Mathematics
1 answer:
vfiekz [6]3 years ago
7 0

Answer:

8

Step-by-step explanation:

You use law of sines, and get: AB/sin(53) = 7/sin(44)

You multiply both sides by sin(53), and get:

AB = 7*sin(53)/sin(44)

That means AB is 8.04776679886, which rounds to 8

To get the other endpoint, we must apply the opposite.

x distance: -7, y distance: -9

(12, -9)

12 - 7 = 5, -9 - 9 = -18

(5, -18)

Help!!!!!!!!!!!!!!!!!!!!!​
Rufina [12.5K]

Answer:

6

Step-by-step explanation:

There are only 6 significant digits because in total there are 9 digits. We do not need the first 2 0's, so now we only have 7 digits. But the question is do we really need the last 0? The answer is no. No, you do not need the last 0 because we already know that it's .0049, and the 0 is just an extra.

So without all the insignificant 0's, the number would look like this:

13.0049
