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:
45 positive numbers have the sum of their digits equal to 8
Step-by-step explanation:
given data
number = 1 to 999
sum n = 8
to find out
positive numbers
solution
we will choose number by this formula
(n+1) (n+2) / 2
here n is 8
so put this value we get number that
positive numbers = (n+1) (n+2) / 2
positive numbers = (8+1) (8+2) / 2
positive numbers = 90 / 2
so 45 positive numbers have the sum of their digits equal to 8
