The tangent of the given angles are the ratios <em>y</em> to the <em>x</em> coordinate of
the point of the terminal side on the unit circle.
The correct options are;
<h3>How to find the points on the unit circle</h3>
The tangent of an angle is given as follows;
First angle
An angle given is; 
Therefore;
The above result can be obtained as follows;
Which is obtained when we have;
Therefore
The required coordinates is therefore;
Second angle
The angle, 
, gives; 
The above value can be obtained as follows;
Which gives;
Third angle
The angle 210° gives; tan(210°) = 
, which can be obtained as follows;
Therefore;

Simply you can answer it
area of trapezoid= area of triangle + area of triangle + area of rectangle
so,
area=( 1/2*2*12)*2+12*14
=24+12*14
=192in²
They will both have the same amount in the bank after 10 weeks
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change, slope or gradient
<h3>How to determine the solution to the system?</h3>
A system of linear equations is a collection of at least two linear equations.
In this case, we have
<u>Nancy</u>
Initial = 400
Rate = 10
So, the equation is
y = 400 + 10x
<u>700</u>
Initial = 700
Spending = 20
So, the equation is
y = 700 - 20x
When they both have the same amount of money in the bank, we have
700 - 20x = 400 + 10x
Evaluate the like terms
30x = 300
Divide by 30
x = 10
Hence, they will both have the same amount in the bank after 10 weeks

First subtract the original high from the new high:
567 - 540 = 27 more vacuums sold.
Now divide the increase amount by the original high and multiply that by 100 to get the percentage:
27 / 540 = 0.05
0.05 * 100 = 5% Increase.
