Answer:
x = 2k
is the solution of this equation.
Step-by-step explanation:
This question is related to trigonometric equations.
The given equation is,

We have to find the solutions of this equation.
Put 
+ 3cosx - 1 = 2
= 0
For this equation only cosx = 1 is possible solution.
Cosx = 1 happens when x is a multiple of 2
So x = 2k
is the solution of this equation.

Answer:
7/10
Step-by-step explanation:
3/10+2/5=3/10+4/10=7/10
You can use number patterns to find the LCM of 120 and 360 by multiplying 120 by 1,2,3,4,5,6,and so on and do the same with 360 until you find the least number that they have in common.
