You can use the identity
cos(x)² +sin(x)² = 1
to find sin(x) from cos(x) or vice versa.
(1/4)² +sin(x)² = 1
sin(x)² = 1 - 1/16
sin(x) = ±(√15)/4
Then the tangent can be computed as the ratio of sine to cosine.
tan(x) = sin(x)/cos(x) = (±(√15)/4)/(1/4)
tan(x) = ±√15
There are two possible answers.
In the first quadrant:
sin(x) = (√15)/4
tan(x) = √15
In the fourth quadrant:
sin(x) = -(√15)/4
tan(x) = -√15

20% of 2100 is 420
So the tax is $420
Then 2100-420= 1680
So he has $1680 left after paying the tax.

The equation of a line with slope 2/3 and point (0,2) is 3y - 2x = 6
The equation of a line is given as
m = slope
c = intercept
The data given are
- slope (m) = 2/3
- x = 0
- y = 2
<h3>Intercept</h3>
Put in the values into the equation above and solve for the intercept.
<h3>Equation of the line</h3>
Multiply through by 3
From the above calculation, the equation of a line is 3y - 2x = 6
