X=63
Explanation: Add the two given sides, you get 27, since the triangle is a right angle you would subtract 27 from 90.
90-27=63
                                
             
                    
              
              
                
                
Answer:
Step-by-step explanation:
Comment
You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle
Equation
Cos(x) = a/c the way you have labeled it.
Givens
a = 9
c = 18
Solution
Cos(x) = a / c
Cos(x) = 9 / 18
cos(x) = 1/2
x = cos-1(1/2)
x = 60 degrees
Answer
x = 60

Answer:
This is an equation. 
Step-by-step explanation:
An expression would mean that there is no equal sign, but since there is, that makes it an equation.
