How do you find a tangent

Step-by-step explanation:

Tangent is a line in the plane of a circle which intersects it in only one point.

If line AB intersects a circle with centre O at point T, then line AB is tangent to the circle at T.

General Tangent

A tangent is a straight line that touches a curve in only one place. To find the equation of a tangent, you would have to

- Find the point on the curve that the tangent line touches

- Find the slope of the line at that point

- Use the slope intercept formula to find the equation of the tangent line

To find the slope, you could

- Use derivatives

- Calculate the slope using two points on the tangent line

Tangents in Trigonometry

In trigonometry, the tangent of an angle is equal to the length of the opposite side divided by the length of the adjacent side in a triangle

- tan = opposite / adjacent

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
