Answer:
x = 16
Step-by-step explanation:
The angle opposite of 4x will have the same value. So set up an equation of 4x is equal to the opposite angle.
4x = 64
Then solve for x
x = 16
Answer:
The roots of the given equation is x=4,3i,-3i
Step-by-step explanation:
The given cubic equation is

To find the roots we have to equate the equation to zero
ie, 
It can be done by using Synthetic division method
Therfore [tex](x-1) is not a factor or root
now put x=-1
Therfore [tex](x-1) is not a factor or root
similarly let x=2,-2,3,-3 all not equal to zero so the are not roots.
let x-4 is a factor of given equation
then it satifies the equation ie (x-4) is a root
And it may be written as
[tex](x-4)(x^2+9)
