Tan(-4pi/3) = 0.0731897502
Answer: 5940
Step-by-step explanation: I don't know if it's for sure right but here
First I knew 10,800 was 100% and I wanted to find 2.5%
So I did:
10,800 divided by 100 and I got 108 = 1%
Than you want to do
108 x 2.5 = 270 ( 2.5% )
After that you wanted to find out how much years apart so
2021 - 2003 = 18
Then
18 x 270 = 4,860
Last of all you have to do
10,800 - 4,860 = 5940
let's recall that in a Kite the diagonals meet each other at 90° angles, Check the picture below, so we're looking for the equation of a line that's perpendicular to BD and that passes through (-1 , 3).
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of BD


so we're really looking for the equation of a line whose slope is -1/3 and passes through point A

I think the answer is
A.) infinitely many
The answer is 3 29/36
5 3/12 = 5 9/36
1 4/9 = 1 16/36
So the answer equation is 5 9/36 - 1 16/36
down: 4 45/36 - 1 16/36 = 3 29/36
I HOPE THIS HELPS
