The question says that KN bisects JKL. This means that the angles are exactly equal. Thus, we can set the angles equal to each other to solve for x:

x + 30 = 3x - 50
30 = 2x - 50
80 = 2x
x = 40

Your answer is B. 40.

What is the correct definition for tan 0

Reptile [31]

$tan\theta=\frac{sin\theta}{cos\theta}\\\\\\Look\ at\ the\ picture.\\\\In\ a\ right\ triangle:\\\\sin\theta=\frac{a}{c};\ cos\theta=\frac{b}{c};\ tan\theta=\frac{a}{b}\\\\\frac{sin\theta}{cos\theta}=\frac{\frac{a}{c}}{\frac{b}{c}}=\frac{a}{c}\times\frac{c}{b}=\frac{a}{b}=tan\theta$

If the composition of two functions is:

You are correct! The problems that can arise with a function domain are:

Denominators that become zero
Even-degree roots with negative input
Logarithms with negative or zero input

In this case, you have a denominator, and you don't have roots nor logarithms. This means that your only concern must be the denominator, specifically, it cannot be zero.

And you simply have

$x-3\neq 0 \iff x \neq 3$
