Answer:
x=3.414 and x=0.59 is the desired answer.
Step-by-step explanation:
We are given a quadratic equation as : 
on dividing both side by 2 we have the equation as

on solving for the roots of the equation using the quadratic formula we get that 
and 
x=2+1.414 and x=2-1.414
Hence , x=3.414 and x=0.586≈0.59.
The answer your looking for is 5
Remember how the tangent function is defined as

Now where exactly are the vertical assymptotes? Well, where cosx = 0, because anything over 0 is undefined, and where a value is undefined, you are required to draw a vertical assymptote.
Now where exactly are the x interecepts? Well, where sinx = 0, because remember, an x-intercept is where y = 0, or where it crosses the x-axis, meaning where the tangent function is equal to 0.
So the x-intercepts are at where sinx = 0.
Answer:

Step-by-step explanation:
The reference angle is an acute angle that angle in standard position makes with the positive x-axis.
The given angle in radians is

This angle is already acute and hence it is itself a reference angle.
The reference angle of any angle in the first quadrant is the same angle.
