1 is the only number that won't duplicate a value.
123.875 i think is the answer
Answer:
x = 30 degrees
Step-by-step explanation:
cos (x) = sqrt(3)/2
We need to take the inverse of each side
cos ^-1( cos x) = cos ^-1 (sqrt(3)/2)
x = cos ^-1 (sqrt(3)/2)
x = 30 degrees
In a mathematical sense..
Not to make it too complicated, however, here's where we get on to the real mathematics.
There are infinite equations for 2 + 2. The gap between any number can be infinite if you keep giving it more numerical content. However, solving 2 + 2 can be very tricky.
1 + 1 + 1 + 1 = 4. Easy, right? Wrong. We can deduct from this equation that 1 + 1 = 2, so if we do 1 + 1 PLUS 1 + 1, (1 + 1 + 1 + 1 again), that equals four, because 1 + 1 is 2 and if we add another 1 to 2, 1 + 2, it equals 3, so 1 + 3 = 4. I'd like to remind you-- this works both ways, whether or not it's 3 + 1 or 1 + 3, it equals 4. If we carry the 1 from the three and put it in a separate number in an equation, said equation is now 1 + 1 + 2. It still equals 4, because 1 + 1 = 2 and if you take 2 and put it in 1 + 1's place, it's 2 + 2.
2 + 2 = 4.
(this was a joke answer, don't take anything said in this answer seriously.. OR you can if you want, because it's all true.. 2 + 2 = 4.)
Hope this helped!

You can simplify the equation:
To find the solution in a value of x you substitute the x by the given value:
x=-2
x=0
x=5
