Answer 
sqrt(108)
6 sqrt(3)
10.3923
I don't know which answer you  want.
Step-by-step explanation:
- Drop a perpendicular from the top angle to the base. 
 - The base is cut into 2 equal parts.
 - Each part is 12/2 = 6
 - The perpendicular, as its name implies, meets the base at 90o.
 - You can use the Pythagorean Theorem to find the height.
 
h^2 = side^2 - (1/2 b)^2 
h^2 = 12^2 - 6^2
h^2 = 144 - 36
h^2 = 108
Take the square root of both sides
h = sqrt(108)
h = sqrt(2*2 * 3 * 3 * 3)
h = 2 * 3 sqrt(3)
h = 6sqrt(3)
h = 6 * 1.7321
h = 10.3923
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
The tangent to the angle makes an angle of 90° with the radius.
The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.
By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore
x = 60-30 = 30°.

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
