Given right triangle def, what is the value of tan(f)  9/41  40/41  40/9   41/9

Option C is correct.

The branch of mathematics which concerned with the specific function of angles and their application.

Given

Right triangle DEF.

Tangent of F.

We know the tangent,

Perpendicular = 40

Base = 9

Then

Here the tangent of F is .

Thus, option C is correct.

More about the trigonometry link is given below.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

hello i might . what do you need.
